Abstract

A slide member (7) is screwed to a flange portion (8), and an orifice-like plate (9), a polishing-stone holder (10), and a polishing- stone hold-down member are screwed to the flange portion (8). The polishing-stone holder (10) and the polishing- stone hold-down member (11) are screwed together with a different screw from the above. Alumina-ceramic polishing stones (12) are arranged between the polishing-stone holder (10) and the polishing-stone hold-down member (11). When a holder (4) and a pin chuck (5) surface are separated from each other, the polishing stones (12) are maximally projected from the holder (4). While when a chuck-cleaning device (1) is lowered to a state where the polishing stones (12) and the pin chuck (5) surface are in contact with each other, the polishing stones (12) are retracted adapting themselves to the pin chuck surface. Further, even if the pin-chuck (5) surface has undulation (projections and depressions), each polishing stone (12) comes into contact with the surface, adapting itself to the projections and depressions. This makes it possible that minute foreign substances are effectively removed from the surface of a portion for holding an object to be polished.

[Prior art] Examples of crystals It is known that a processing device for processing a workpiece using a processing tool is used for various processing such as grinding, grinding, polishing, and the like. The rounded object is a semiconductor wafer, the processing tool is a chemical mechanical polishing device (cMp device) composed of a polishing pad for surface polishing of a semiconductor, and a CMP (Chemical Mechanical Polling) device is conventionally used for Manufacturing process of semiconductor components. The CMP device is a polishing process for polishing and flattening a film formed on a wafer surface in a semiconductor wafer manufacturing process (for example, polishing an interlayer insulator, polishing a surface metal film, and polishing a dielectric film). Etc.), it is required to polish the wafer surface after the rubbing polishing process, so that a uniform and flat film layer of a predetermined thickness remains on the wafer surface. In addition, CMP apparatuses are disclosed in, for example, Japanese Patent Laid-Open Publication No. 03-31-52 (Patent Document D 'Japanese Patent Laid-Open Publication No. 1 1-204468 (Patent Document 2)). Refer to FIG. 8 and FIG. 9 describes the CMP device as described above. The CMP device 31 has a plurality of polishing heads, which are supported by the polishing head transfer mechanism 37 so that the polishing surface faces downward. The polishing heads are made of rough polishing polishing heads 32a, The middle grinding head 32b and the last grinding head 32c (but: 'The final grinding head is not shown in the figure, and the symbol 32 is used. M is re-introduced] This is a description of the grinding head 32. The head 32 俜 is sent from the grinding head transfer mechanism 37 to the corporal ^ head ^ is an extension of the rotation axis M and is driven by a motor (not shown) in the grinding, evening, and 37. "员 32 The lower part has a pad holding mechanism. The polishing pad 34 (general name of polishing 34a, 34b, and 34c is referred to as ^ 疋, 32c is not shown in the figure). The polishing head 32b and the final polishing head 32c during polishing are relatively thick. The polishing head 32a is large, and the polishing is performed among these The head is moved, and the final polishing head 32c is provided with a middle polishing pad 34b and a final polishing pad which are larger than the rough polishing pads *. The bottom is held by a cymbal holding mechanism and can be detachably installed. The lower end of the grinding head 32. In this case, the formation of the grinding poplar for rough grinding is smaller than the grinding head 32b for the middle grinding and the grinding coffee for the final grinding, and a small diameter is installed in the grinding head 32a for the coarse grinding soil. Polishing polishing pad 34a. The rough polishing polishing pad 34a is used to locally polish the surface of the wafer w to be polished, correcting the unevenness of the film thickness on the surface, and polishing the wafer to flatten the surface. The surface has a sufficiently small diameter. On the other hand, the polishing pad 34b for medium polishing and the polishing pad for final polishing are used to correct the unevenness of the surface film thickness by the polishing pad 34a for rough polishing, and to flatten the wafer. The surface of w is uniformly polished, and has a size that covers a wide part or the entire surface of the wafer w. That is, as shown in FIG. 9, the polishing pad 34b for medium polishing has a diameter larger than the radius of the wafer w and covers it. A large part of the surface Size, or a size that covers the entire surface of the wafer with a diameter larger than the diameter of the wafer W. 200413130 The polishing pad 3 4 c for final polishing, not shown, has the same structure. A pad adjustment mechanism is provided in the CMP apparatus 31 35. Here, the polishing pad 34 is trimmed. The pad adjustment mechanism 35 is provided with a dressing disc 35a, a spray nozzle 35b, and a rotatable cleaning brush 36 as shown in the figure. The polishing head transfer mechanism 37 has a holder 37a, The feed screw 37b and the moving body 37c screwed to the feed screw are attached to the moving body 37c via the rotation shaft 33. The feed screw 371) passes through the gear 37d and is rotationally driven by the motor 37f to move the moving body 37c in the X direction shown in Fig. 9. In addition, the polishing head 32 is moved up and down in two directions shown in Fig. 9 by a lifting mechanism (not shown) provided in the transfer 37c. Each of the polishing heads 32a, 32b, and 32c is provided with the above-mentioned mechanism. Although they move independently in the X and z directions, the rough polishing head 32 & is also moved in the y direction orthogonal to the X and Z directions. Make up. . Further, a CMP apparatus 3 is provided with a storage box 39 'for accommodating the crystal circle W of the object to be polished, and a Japanese yen transfer robot 4G for carrying the wafer w to the storage box 39. The wafer transfer robot 40 is a robot for transferring the wafer IB W in the 39 胄 纟 polished state to the indexing table 42 i and carrying out the wafer w after the polishing is completed. The wafer temporary placement table 41 temporarily placed by W. . Knife degree. 42. It is provided with a wafer chuck mechanism 50 with a shaft 42e as an axis and equidistantly spaced on the same circle, and this bismuth rotation is divided into: the wafer loading and unloading area shown by the symbol S1; the symbol The rough grinding area shown by S2; symbol) is not among the grinding areas; the final grinding area shown by symbol S4. Therefore, each of the wafer turning mechanisms 50 sequentially moves to the grinding zone S3, the last yen loading and unloading zone S1, and the coarse grinding zone S2 to the grinding zone S4 according to the rotation of the indexing table 42. In addition, the rough polishing pads held in the rough grinding pad 帛, and the middle polishing pads are held above the rough polishing zone S2, the middle polishing zone S3, and the final polishing zone S4.塾 Can keep the final polishing 塾% for the final polishing 131c. Said round conveying machine ☆, Ren 4Q is also used as an unloading transfer robot for transferring wafers that have been polished. The wafer transfer robot transfers the polished wafers W to the belt conveyor. On 46, it is transferred to the wafer cleaning mechanism 47 by the belt conveyor 46 for cleaning. It also has a chuck trimmer 44a for trimming and cleaning each wafer chuck mechanism 50 of the indexing table 42, and a chuck cleaning mechanism 4. If the flatness of the wafer chuck is not good, when the wafer is clamped, the defects of the flatness will be transmitted to the surface side of the wafer. In this state, the wafer surface is polished to be flat and removed from the chuck. In the case of a wafer, the flatness will be in a bad state. Therefore, in precision grinding, the flatness of the surface of the wafer chuck (chuck) is required. However, a face-up polishing device, that is, a polishing device that polishes a wafer with its polishing surface facing upward, includes a polishing agent (s 1 urry) used in the polishing step, or grinding chips, There is a possibility that tiny foreign matter such as dust may remain on the thimble type head loss surface. In particular, in the case of using abrasive d B's which are easy to agglomerate, even if the top surface of the thimble type chuck is wet, the abrasive tends to solidify. If CMP polishing is performed in this state, polishing is performed with a small foreign matter sandwiched between the 200413130 thimble-type chuck surface and the wafer. Therefore, in the portion where the small foreign matter exists, the flatness is significantly deteriorated. phenomenon. In addition, if a new wafer is loaded without cleaning and drying the thimble-type central head, the cleaning side operating device (effector) of the wafer transfer robot may be contaminated. Furthermore, if wafer adsorption is performed on the thimble-type chuck, in addition to pure water or abrasives on the thimble-type chuck, the adsorption force becomes unstable, and a wafer with surface tension is also generated. The alignment accuracy decreases. The top chuck cleaning unit is needed for the above reasons. It is known that by using the collet cleaning mechanism 44b, after the grinding is completed, the thimble-type chuck head is washed with pure water south pressure, or the millstone with a diameter of -half or so is wiped on the thimble-type while rotating. The surface of the chuck is used to perform these micro: foreign matter removal. … In Japanese Patent Laid-Open Publication No. 2_93762 (Patent Document 3), § an example of such a thimble-type collet cleaning mechanism (chuck mechanism repairer) is included. In this thimble-type chuck mechanism repairer, a ring-shaped ceramic (grinding stone) is fixed to a base plate, and the plate is supported by a rotating shaft and rotated by a rotation drive of a motor. Finishing the wafer grinding 'The wafer is removed and the ring-shaped ceramic of the true chuck cleaning machine becomes empty on the thimble type chuck mechanism to drop to contact the thimble type chuck mechanism = the side supplies the washing water to the wafer surface, Rotate the ring pottery to wash = noodles, wash and grind abrasive particles. During this period, the thimble-type central sheet system was rotated. Using the method described above, the tiny foreign matter adhering to the surface of the thimble-type clamp mechanism is removed. (Patent Literature 1) Japanese Patent Laid-Open No. 1 (), 152 200413130, Japanese Patent Laid-Open No. 11-204468, Japanese Patent Laid-Open No. 2GG2_ 93762 (Patent Literature 2) (Patent Literature 3) [Contents of the Invention] However The surface of the thimble-type chuck mechanism is six to ten and ten to the tenth of the king, and there are undulations (bumps). In addition, the surface ceramics of the ring-shaped ceramics, which have the function of grinding and making vermiculite, are not completely flat, and there are undulations (concavities and convexities). In addition !: The surface of the mechanism and the surface of the ring-shaped ceramics with the function of grinding stone are not parallel to the Yuan Wang. Therefore, 'i.e. the micro foreign body is removed by grinding the thimble with the μ μ', because the two only contact the local area, the untouched part of the two is produced * or the untouched part is generated due to the fluctuation of the two: It is extremely difficult to completely remove tiny foreign bodies. If tiny foreign matter is left on the surface of the thimble-type chuck if it is not removed, the wafer is loaded on the thimble-type chuck, because the wafer has the effect of the convexity of the surface of the thimble-type chuck caused by the flexibility of the foreign matter. Convex. The wafer j is polished in this state to make the wafer surface flat.

A small dimple (d i mp 1 e) -like concave part. The invention with less cost is less than the above case. · Gan 1 θ chop h, the problem is to provide: a watch pin can only be removed from the chuck (grinding object holding part); the surface of the mill can effectively remove small foreign matter, And the semiconductor device manufacturing research using the grinding device to solve this problem, the first hand spear i is a slave device, which is a kind of grinding device while maintaining the object to be held in the holding part, and pushing the dry mouth P into 仃%, while The grinding object is pressed against the object to be polished, and the grinding object is moved relative to the grinding object and the grinding object is moved relative to the grinding object in 200413130. The grinding object is characterized in that: a cleaning device is provided, Hold the surface of the holding part of the object to be polished, while cleaning liquid is supplied to the surface of the holding part, and clean with a grindstone. The grindstone mounted on the cleaning device is opposed to the surface of the holding part and assembled on the holder. A plurality of grindstones 'The holder is rotatably held on the main body of the grinding device by a holding mechanism; and a profiling machine is provided =)' so that the grindstones imitate the surface of the holder (please specify Wai Wai In this method, instead of using a ring-shaped large grindstone as in the conventional technique, a plurality of small grindstones are mounted on a holder, and by rotating the holder, the surface of the holding part holding the object to be polished is ground with a grindstone. The tiny foreign matter is peeled off and rinsed with a washing liquid. Moreover, because of the fact that the various grinding stones of δHai Temple are imitated and maintained: the surface contouring mechanism 'even if the holder is not parallel to the surface of the holding part, it is' r-shaped' and 'even' In the case of undulations (concavities and convexities) on the surface of the holder or the holding part, the small grindstone imitates the inclination or unevenness of the surface of the holding part, so the contact between the surface of the grindstone and the surface of the holding part becomes good. Can effectively remove small foreign matters from the surface of the object holding portion of the object to be polished. Although the term "徂, μ ,,, r., T ^ is ground by holding 0 保持" is used in this specification, it is adhered to the surface of the holding portion. The study of the degree of peeling of small foreign objects is σ, which is a polishing that wipes the surface flat.… Small grinding does not mean that the surface is used to solve this problem? ^ ^ ^ ^ ^ 2 hands & 1 means of the millstone The hardness is lower than that of the holding part P (No. 2 in the scope of the patent application) 12 ZUUH-11 The owner of the hand and 'the hardness of the grinding stone is higher than that of the holding part; The hardness of Health 1 is low, and the wear of the holding part itself is reduced. In the third means to solve the problem, the imitation is incorporated in the first means or the second means to keep the grinding stone capable of holding The structure is set in a predetermined range so that "" applies the spring pressure in the direction of the big out (the scope of the patent application is the third item). This hand slave, because it has the grinding stone from the spring pressure retaining mechanism, is old g 卩 # # & The 苒 & that springs in the direction, even on the surface of the holder and the holding part, and even in the shape of the holder or the companion. Fan Γ oblique or uneven. In addition, because the transportation is restricted, even if the holder is expanded, the grinding stone will not fall off. The fourth means to solve this problem is to install a liquid infiltration prevention member on the first grinding stone, and use the 3rd hand & order in the beta bomb mechanism (please patent for towels) Item 4). (2) Stop the washing material from contacting the two. = The washing liquid will not adhere to the bomb, so it can prevent use, structure, and malfunction due to the adhesion of the washing liquid. The fifth method to solve the problem is in this method. The profiling mechanism is connected to the step-by-step, and has a universal joint mechanism. … The holder and the holding mechanism In this method, even if the holder and the surface of the holding part are not parallel, when these components are in contact with each other, the universal joint mechanism

Touch the part. With this, the 6th-hand γ 々 profiling mechanism, which is used to solve this problem, has the flexibility between the structure (the 6th structure in the scope of patent application and the holder) In this method, even when the holder and 'these components are in contact with each other, the situation of t is not a thousand T T T is caused by the elasticity of the elastomer? Μ ^ When observed, the two surfaces can be connected to each other, and the right side can be maintained It has a certain right shape, even if there are undulations (concavities and convexities) on the surface of the holding part-the receiving surface imitates the surface of the holding part. I. This is the seventh means for the grinding stone to solve this problem. In the arbitrage of means- means, the plural match: When the paragraph to the 6th turn, the h of each millstone is set to 'When the holder has the item from the range 7). 2. The traces of the green traces overlap each other (patented for green: thand & when the holder rotates, the surface of each millstone is painted in such a way that the gates weigh S each other, so the surface of the holding part can be left Grinding at any gap. 4 W person: The eighth means to solve this problem is the outermost range of the grinding stone installed in the 1st hand Ding + any other Feng P ϋ zhongzhong The circumference is straight from the force 1/2 of the straight part of the holding part, and the profit range item 8 is set so that the millstone is located in the range from the center to the outer periphery). In August, when the grinding of the holding part is to be performed, the holding part is rotated. In these 14 200413130 cases, if the holder is configured as in this method, the holder is forced to rotate, so there is no need to supply: the rotating part of the 2 holding part can make the power of holding Γ Γ "holding, condensing, this article m It ’s early to attack. Also, "The holding unit can tolerate a range error. Χ, in :, effectively rotate to power rotation. &Amp; 'You can also use the ninth means to solve this problem, It is attached to the holding mechanism. In the _ # M 目 ^ w 8 method, the center of _: the rotation shaft can rotate around the rotation of the holding part to hold the holder (patent application scope; rotation 9 bis rotation axis,… turned to the holding part, while turning to the rotating part of the holding part: 敁 holding tool then edge * grinding the holding part. Furthermore, when the holding part is rotated, this: more = hook two reasons and The rotation force of the holder is also obtained from the rotation force of the holding part: ::: Special power for revolution is required to make up the structure. Second, the power mechanism for supplying the revolution force. Tian ',,,, can also be set up to solve the problem. The tenth means of the project to supply the cleaning solution to the insurance :: brother In the paragraph, the relative position of the rotation axis of the appliance is: rotation, rotation 'moved in accordance with item 10 of this holding range), 移动 (movement of a patent in this means' accompanied by the rotation axis of Baoya eight holders) Keeping ^, the positional relationship between the washing liquid supply mechanism and the security is revolved. By this, because the positional relationship between the holder 15 and the cleaning liquid supply mechanism is unchanged, it is possible to grind the cleaning liquid pair It is supplied from a certain position, so it can maintain the stability of cleaning. The eleventh means to solve this problem is a method for manufacturing a semiconductor device, which is characterized by using any of the first means to the tenth means. Step of polishing the wafer by means of a polishing device (the nth item in the scope of the patent application) In this method, because the wafer polishing step in the semiconductor element manufacturing process does not polish the wafer well, it is possible to manufacture semiconductors with a high yield. Element 0 [Embodiment] Hereinafter, an embodiment of the present invention will be described using drawings. Fig. 丨 is a cross-sectional view showing the outline of a first chuck cleaning device used in the embodiment of the present invention. The clean device i 'includes: a rotating arm 3 (the shaft is supported by the grinding body f2 and can rotate)' and a holder 4 (the shaft is supported by its rotation # 3). The gp rotating arm 3 is a thimble type of the object to be ground. The chuck 5: the state where the rotation center is consistent with the rotation center, and the shaft is supported by the grinding device body :: a holder support member 6 is installed on the rotation arm 3, which is held by the eighth support member 6 & and the second The holder support member 6b is composed of the holder support member 6b 'after the movable structure. The holder support member 6b' can slide between the ring-shaped sliding member 7 while touching the ring-shaped sliding member 7. The surface such as polyethylene is easy to slide. It is made of materials that are not dusty and do not easily burn. The sliding member 7 is fixed to a plate 9 with screws, the grindstone holder 10 and ::. " At the flange portion 8, the stone clamps 11 are locked together. The plate 9 and the grindstone holder are fixed by 16 = different screws ’. The pressing tool u is fixed with screws, and the grindstone holder 丨 is here. The grinding stone 12 is sandwiched between the grinding tool & plate 9 and alumina ceramic. The material of the millstone κ can be suitable for use by oxidized ceramics and general users. The hardness of the grindstone 12 is preferably lower than that of the thimble-type chuck 5. This is because the abrasion of the thimble-type chuck 5 itself can be reduced during cleaning. The upper cover 13 and the lower cover 14 are fixed to the flange portion 8 'with screws. In addition, although it is not directly related to the present invention, the 'rotating arm 3 and the i-th holder supporting member 6a form a hollow, and the hollow washing liquid (purified water, etc., generally used) is supplied to the lower cover 14 The space is supplied to the thimble type chuck 5 from a supply port (not shown). As can be seen from FIG. 1, in this embodiment, the diameter of the outermost circle of the portion where the grindstone 12 is provided in the holder 4 is about I / 2 of the diameter of the thimble type collet 5, and the range where the grindstone 12 is provided. It covers the range from the center to the outer periphery of the thimble collet 5. FIG. 2 shows a detailed view of part A of FIG. 1. The grindstone 12 passes the grindstone holder 10, presses the grindstone pressing tool 11 against the reference surface, forms a U-shaped recess on the upper part of the grindstone 12, and fills the elastic body 16 such as NBR with a thickness of The gap 17 is sandwiched by a plate 9. The gasket 15 is provided on the grindstone pressing tool II 'to prevent the abrasive or pure water from penetrating into the grindstone 12. In addition, instead of the pad 15, a rubber plate of a bellows shape may be provided to connect the graphite grinding tools 11 and the grinding stones 12 to prevent the gap between the grinding stone pressing tools 11 and the grinding stones 12.

In addition, the holder can be made larger than the ejector chuck (grinding object holding portion). 7, which indicates the manufacturing process of semiconductor devices according to the embodiment of the present invention, and the semiconductor process is started. First, in step S200, select an appropriate processing step from the following steps S2 (H to S204), and proceed to any step. 21 200413130 Here Step S201 is an oxidation step of oxidizing the wafer surface. Step S202 is a CD step of forming an insulating film or a dielectric film on the wafer surface by CVD or the like. Step S203 is electrode formation of an electrode formed on the wafer by evaporation or the like. Step. Step S204 is an ion implantation step of implanting ions on the wafer. After the CVD step (S202) or the electrode formation step (S203), the process proceeds to step S205. Step S205 is a CMP step. In the CMP step, the polishing device of the present invention is used to planarize the interlayer insulating film or the metal film on the semiconductor element surface, and to form the damascene by polishing the dielectric film. After the CMP step (S205) or the oxidation step (S201), the process proceeds to step S206. Step S206 is a lithography step. In this step, a photoresist is coated on the wafer, and the circuit pattern of the wafer is fired by exposure using an exposure device, and the exposed wafer is developed. Furthermore, the next step 8207 is an etching step, which removes parts other than the developed photoresist image by etching, and then performs photoresist stripping to remove the photoresist that has been etched and becomes unnecessary. Next, it is judged in step S208 whether all the required steps are completed. If it is not completed, it returns to step S200, and repeats the foregoing steps to form a circuit pattern on the wafer. If it is determined in step S208 that all steps have been completed, the process ends. According to the method of manufacturing a semiconductor device of the present invention, since the polishing process of the present invention is performed in the CMP step, the yield of the CMP step is improved. This has the effect that it is possible to manufacture a few semiconductors at a lower cost than the known method of manufacturing semiconductor components. It is also possible to use the polishing device of the present invention in a CMP step of manufacturing semiconductor devices other than the semiconductor device manufacturing process described above. In addition, the semiconductor device manufactured by the method for manufacturing a semiconductor device according to the present invention is manufactured at a high yield, and thus becomes a low-cost semiconductor device. As described above, according to the present invention, it is possible to provide a polishing device capable of effectively removing minute foreign matter from the surface of a T-needle-type central head (a polishing object holding portion), and a method of manufacturing a semiconductor device using the polishing device.
