Definitions
- the present invention relates to a method for electron beam-induced deposition of conductive material.
- the composition of the deposited material contains not only the metal central atom but also carbon and oxygen from the CO ligands of the metal carbonyl.
- the composition of the landfill - and of course its specific electrical resistance - thus depends on the process control in the case of electron beam-induced deposition.
- the authors Lau, Chee, Thong and Ng have deposited conductive dicobalto-carbonyl needles under various process conditions with the aid of an electron beam and analyzed the samples (YM Lau, PC Chee, JTL Thong to V. Ng, "Propertiers and applications of cobalt-based Material produced by electron-beam induced deposition ", J. Vac., Technol.
- the present invention is therefore based on the problem to provide a simpler method for electron beam-induced deposition of conductive material from a metal carbonyl, which avoids the disadvantages and limitations mentioned above, at least in part.
- the method of electron beam-induced deposition of electrically conductive material comprises providing at least one electron beam at a location of a substrate, storing the at least one metal carbonyl at a first temperature, and heating the at least one metal carbonyl to at least a second temperature prior to Providing at the location where the at least one electron beam impinges.
- the Applicant has surprisingly found that, besides the parameters of the electron beam, the treatment of the metal carbonyl has a decisive influence on the deposition of conductive material.
- a spontaneous transformation of a metal carbonyl for example from Dikobaltoktocarbonyl (Co 2 (CO) 8 ) in tetra cobalt dodecarbonyl (Co 4 (CO) I2 ) to form Kohlenstoffnonooxid Avoid (CO).
- CO room temperature
- dicobaltoctocarbonyl (Co 2 (CO) 8 ) is used as metal carbonyl.
- metal carbonyl for example with one of the metal central chromium (Cr), iron (Fe), manganese (Mn), molybdenum (Mo), nickel (Ni), tellurium (Te), rhenium (Rh), ruthenium (Ru), vanadium (V) tungsten (W), etc. are used.
- Cr metal central chromium
- Fe iron
- Mo manganese
- Mo molybdenum
- Ni nickel
- Te tellurium
- Rh rhenium
- Ru ruthenium
- V vanadium
- W vanadium
- the first temperature for the metal carbonyl ranges from 230K to 320K, preferably from 240K to 290K, and more preferably from 250K to 260K.
- the ideal temperature is dependent upon the material and constraints imposed by the gas delivery system To be defined.
- the second temperature for the metal carbonyl comprises a range from 265 K to 320 K, preferably from 270 K to 300 K and particularly preferably from 275 K to 280 K.
- the electron beam and the metal carbonyl are used to fill a vias.
- the electron beam has a refresh time of from 20 milliseconds to 0.2 milliseconds, preferably from 5 milliseconds to 0.8 milliseconds, and more preferably from 2.5 milliseconds to 1.6 milliseconds.
- the electron beam at the end of the filling on a smaller, preferably a ten times lower repetition period as at the beginning of the filling.
- the electron beam has a residence time (dwell time) of 2000 nanoseconds to 10 nanoseconds, preferably 500 nanoseconds to 40 nanoseconds and more preferably 250 nanoseconds to 160 at the beginning of filling Nanoseconds up.
- dwell time 2000 nanoseconds to 10 nanoseconds, preferably 500 nanoseconds to 40 nanoseconds and more preferably 250 nanoseconds to 160 at the beginning of filling Nanoseconds up.
- the quotient of repetition time duration and residence time duration when filling a contact hole is increased with increasing aspect ratio.
- the deposited conductive material has a specific resistance of less than 100 ⁇ cm.
- a feed system for the metal carbonyl is formed in order to suck the carbon dioxide formed from the metal carbonyl out of a vacuum chamber.
- the vacuum chamber comprises no additional heat sources in addition to the electron beam.
- the electron beam is used to find the point to be processed and / or to control the deposition of the electrically conductive material and / or its surroundings.
- an apparatus for electron beam-induced deposition of conductive material comprises an electron beam apparatus for providing at least one electron beam at a location of a substrate, a reservoir for storing at least one metal carbonyl at a first temperature, and a device for heating the at least one Metallcarbonyls on at least a second Temperature before providing to a location at which the at least one electron beam impinges.
- Fig. 1 is a schematic representation of an exemplary device for
- Metallcarbonyls and a focused electron beam electrically conductive material can be deposited;
- FIG. 2 is a schematic enlarged view of a via etched from a first wiring plane through multiple layers of a multilayer system to a second wiring level;
- FIG. 3 shows a schematic section through the via of FIG. 2, which has been filled with conductive material by means of an embodiment of the method according to the invention.
- a substrate 90 is arranged in a vacuum chamber 10 on a sample holder 20, on which conductive material is to be deposited.
- the substrate 90 comprises a multilayer system 200.
- the electron beam for carrying out the method according to the invention originates from an electron beam device 30 which is, for example, an optionally modified scanning electron microscope.
- the metal carbonyl used is dicobalt octocarbonyl (Co 2 (CO) 8 ).
- Alternative embodiments of the process according to the invention allow the use of metal carbonyls with other central metal atoms, such as Cr, Fe, Ni, Mo, V and W, to name just a few examples. It is also conceivable to introduce two or more metal carbonyls via a separate valve into the vacuum chamber 10 through a single or separate inlet (not shown in FIG. 1).
- the first and / or the plurality of metal carbonyls may also be introduced into the vacuum chamber 10 in a non-directional manner.
- the metal carbonyl Co 2 (CO) 8 is stored in a reservoir 70.
- the reservoir has a cooling device and a temperature control.
- the contents of the container 70 can be stored at a defined temperature.
- the reservoir 70 allows the Dikobaltoktocarbonyls below the room temperature. It has proven to be advantageous to store Co 2 (CO) 8 at essentially 253 K. At this temperature, a spontaneous conversion of Dikobaltoktocarbonyl in tetraco- baltdodecacarbonyl with the release of CO can be prevented or slowed down sufficiently.
- the device 60 may heat the Co 2 (CO) 8 coming from the reservoir 70 to an adjustable temperature. This is necessary because only the provision of the metal carbonyl at the point of impact of the electron beam on the substrate 90 at sufficiently high temperatures results in the deposition of low resistivity conductive material. It has been found that the supply of dicobaltoctocarbonyl via inlet 40 at a temperature of about 278 K results in conductive material of low resistivity.
- the device 60 further allows the temperature of the Co 2 (CO) 8 to change during the deposition process. Since the favorable inlet temperature for dicobaltoctocarbonyl is below room temperature, in an alternative embodiment, the energy needed to heat the metal carbonyl may also be taken from the environment, the device 60 may be configured to allow heating of the metal carbonyl in this way. It is also conceivable that the device 60 combines both described possibilities of heating in one embodiment.
- valves 50 in the delivery system 40 allow for the provision of a defined gas flow rate at the point of impact of the electron beam on the substrate 90, or the controlled supply of Co 2 (CO) 8 from the reservoir 70 into the heater 60.
- the metal carbonyl is continuously provided at the location of the electron beam.
- the valves 50 make it possible in an alternative embodiment. It is possible to vary the flow of gas in the delivery system 40 over time.
- the suction device 80 shown in FIG. 1 This makes it possible to suck the carbon dioxide formed in the electron beam from the metal carbonyl substantially at the place of origin out of the vacuum chamber 10. Since the CO 2 is locally pumped out of the vacuum chamber 10 at the point of impact of the electron beam on the substrate 90 before it can disperse and settle therein, contamination of the vacuum chamber 10 is prevented.
- the metal carbonyl feed system 40 and the carbon dioxide exhaust 80 may be combined in one system, for example, by two side by side tubes; cannulas.
- a focused electron beam For initializing the etching reaction, preferably only a focused electron beam is used.
- the electron acceleration voltage is in the range of 0.1 keV to 30 keV.
- the current intensity of the electron beam used varies in the interval between 1 pA and 1 nA.
- other energy-transferring mechanisms eg a focused laser beam and / or or an unfocussed ion beam.
- Electron beam induced deposition is used in addition to mask repair, primarily for wiring or rewiring microelectronic circuit parts and for directly depositing conductive interconnections between microelectromechanical systems (MEMS).
- MEMS microelectromechanical systems
- Various embodiments of the method according to the invention can be used for the mentioned different fields of application. In the following, a preferred embodiment for the filling of deep vias with a high aspect ratio for connecting microelectronic circuit blocks is explained in more detail.
- the aspect ratio refers to the ratio of the depth or height of a structure to its smallest lateral extent.
- FIG. 2 shows a multilayer system 200 which has on its upper side a first wiring plane, of which the electrical line 290 is shown.
- the layers 210, 220, 230, 240, 250 and 280 are in the example of FIG. 2 semiconductor layers of different composition and / or doping. However, it is also possible that one, several or all of the layers 210, 220, 230,
- insulator layer 260 In the insulator layer 260, a second wiring layer is embedded, the metallically conductive connections
- a via 300 is exposed from the first wiring level electric wire 290 to the second wiring level electric wire 270 by etching. As shown in FIG.
- FIG. 3 presents a section through the via 300 of the multilayer system 200 of FIG. 2, after filling it with an embodiment of the method according to the invention.
- the refresh time of the electron beam at the beginning of the deposition process is substantially 2 ms (milliseconds). This parameter decreases towards the end of the filling process at the upper end of the contact hole 300 by about an order of magnitude to substantially 0.2 ms.
- the electron beam remains in one place essentially 200 ns (nanoseconds).
- the residence time is reduced substantially to 100 ns.
- the electron beam had an energy of 1 keV and its current strength was in the range between 1 pA and 50 pA.
- the diameter of the Electron beam was about 4 nm. The term "substantially” means here, as well as in the other parts of this description an indication within the measurement accuracy.
- the quotient of repetition time duration and dwell time during the filling of the contact hole 300 changes.
- This quotient also shows a dependency on the aspect ratio of the contact hole to be filled. With increasing aspect ratio, it is beneficial to achieve low resistivity landfills to increase the quotient of repeat time and residence time.
- the method according to the invention makes it possible to deposit material with a specific resistance of less than 100 ⁇ xm. This numerical value is still about 20 times higher than the specific resistance of metallic cobalt. However, the numerical value of the resistivity achieved is of the same order of magnitude as that of Lau et al. Lau, PC Chee, JTL Thong to V. Ng, "Propertiers and applications of cobalt-based material produced by electron-beam induced deposition", J. Vac. Sei. Technol.
