Definitions
- solder balls are often used for mounting the components on substrates.
- the components are usually flip-chip using solder balls on the.
- Mounted substrate wherein contact surfaces for electrically conductive contacting of the solder balls are often present on the substrate.
- the top metal layer that is in contact with the solder balls is often aluminum or a related metal. Due to an electrically insulating aluminum oxide layer present on the aluminum and because of the non-wetting properties of the aluminum for solders, various further metal layers often have to be arranged between the solder ball and the metal layer of the semiconductor component. These ensure good adhesion of the solder balls, for example, and can be wetted with the material of the solder balls.
- This so-called "under bump metallization" (UBM) is frequently applied to the semiconductor chip by means of complex galvanic or other methods. The generation of the under-bump metallization causes a great deal of work and thus cost.
- the object of the present inventive method is to specify a method for producing electrical contacts in the form of solder balls, in which the above-mentioned under-bump metallization is not required and, at the same time, the solder balls can be produced on an electrical component in a particularly simple manner ,
- the invention describes a method for producing electrical contacts in the form of solder balls on a Electrical component comprising a base body, the following method steps being carried out:
- method step A a template is arranged on a base body of the electrical component.
- process step B through holes are created through the template.
- fillings are produced by filling the through-hole with an electrically conductive material to a higher level than the surface of the base body (process step C).
- process step D) the fillings are then cured, which protrude from the base body of the electrical component.
- solder balls for external electrical contacting of the fillings are produced directly on the surfaces of the fillings.
- the method according to the invention specifies a particularly simple method for making electrically conductive contact with areas located inside the component by means of the solder balls.
- the template arranged on the base body serves to mechanically stabilize the base body during the production of the through holes, so that there are no break points in the base body.
- the template enables process step C) of the process according to the invention to fill the electrically conductive material beyond the surface of the base body into the bores, so that in process step D) the fillings can protrude beyond the base body of the electrical component during curing.
- the solder balls can then be produced particularly easily on these protruding surfaces of the fillings (see, for example, FIGS. 1A to 1D). No under-bump metallizations between the fillings and the solder balls are necessary.
- step A) a template with openings gene used and then generated in process step B) the through holes through the openings.
- the template serves as a matrix for producing the through holes and indicates the position of the through holes in the base body, so that particularly simple generation of the through holes is possible.
- a ceramic green body to be used for the electrical component, which is then advantageously sintered together with the fillings in method step D).
- the green body can be sintered at 1000 ° C to 1200 ° C.
- the green body is thus particularly advantageously sintered in one process step and the fillings are cured at the same time.
- a template which comprises a polymer material.
- This can be, for example, a plastic, for example polyphenylene sulfide (PPS) or polyethylene terephthalate (PET).
- PPS polyphenylene sulfide
- PET polyethylene terephthalate
- the template is advantageously an organic film of high stiffness, which mechanically stabilizes the base body and can advantageously be punched.
- the template is evaporated particularly advantageously during the curing of the fillings in process step D) and any sintering of the ceramic green body that may take place, so that it dissolves during this process step.
- the stencil can still hold the not yet hardened fillings in the through holes, but is then removed by evaporation, so that subsequent removal of the film is no longer necessary. Evaporation in the sense of the invention also means decarburization.
- the through-bores can advantageously be produced by means of punching. Punching enables a particularly simple and inexpensive production of the through holes.
- a plurality of electrode surfaces which contain electrodes and are arranged at a distance in the base body can be produced before method step A). Areas of the base body are then located between the electrodes.
- the fillings can then be produced in such a way that they are electrically conductively connected to the electrodes.
- the advantage is that the fillings then serve as electrically conductive vias that connect the electrodes in an electrically conductive manner to the solder balls on the surface of the component.
- the base body by stacking ceramic green foils on top of one another.
- the electrodes can be produced on individual ceramic green foils. This is particularly easy using the printing process, for example the screen printing process.
- the protruding surfaces of the fillings can be treated mechanically and / or chemically. This treatment can serve particularly advantageously to achieve better wettability of the surfaces of the fillings for the solder balls.
- Mechanical treatment can be carried out, for example, by means of lapping and sandblasting.
- Chemical treatment can be carried out using acids and alkalis.
- metal pastes are advantageously used as the electrically conductive material, which include Pd, Pt, AgPd, AgPt and AgPdPt as metals and metal alloys. These metals and metal alloys enable particularly good wettability and adhesion of the solder balls on the electrically conductive fillings.
- the solder balls can be produced, for example, by means of a galvanic process.
- method step E) it is also possible to produce solder balls particularly simply by bringing the surfaces of the fillings into contact with a solder bath.
- the metals or metal alloys are particularly well suited for being applied to the fillings by means of a soldering process.
- a base body can be used in the method according to the invention, which comprises a ceramic material which is, for example, a varistor ceramic based on ZnO-Bi or ZnO-Pr.
- a ceramic material which is, for example, a varistor ceramic based on ZnO-Bi or ZnO-Pr.
- Such an electrical component produced by means of the method according to the invention would then be a varistor, which can be used as a voltage-dependent resistor, for example for overvoltage protection of circuits.
- the ceramic material of the base body can furthermore comprise a ceramic sensor ceramic, which is selected from so-called MPO ceramics, for example (Sm, Pa) MiCd0 3 . These ceramics have temperature-dependent e R values and are not ferroelectric ceramics.
- Ferroelectric ceramics with high dielectric constants, as well as doped barium titanate and so-called barrier ceramics, can also be used. Alles. these dielectric ceramics are described in the book "Keramik” by H. Schaumburg (editor, BG Teubner Verlag Stuttgart, 1994) on pages 351 to 352 and 363, whereby full reference is hereby made to these pages.
- the ceramic material can be selected from thermistor ceramics, for example NTC ceramics, for example nickel-manganese spinels and perovskites.
- non-ceramic materials for example glasses can be used as materials for the basic body in the method according to the invention.

- the base body 1 can comprise different ceramic subareas 1A and 1B, for example different ceramic green foils.
- the base body can include ZnO-Bi.
- the template can consist of organic polymers of suitable stiffness, for example from the class of polyphenylene sulfides (PPS) or polyethylene terephthalates (PET).
- FIG. 1B shows a cross section through a component after method step C) of the method according to the invention.
- An electrically conductive material was filled into the through holes 10 in such a way that the surface of the fillings 15 is arranged in the through holes at a higher level than the surface of the base body.
- the template 5 is suitable, for example, for retaining electrically conductive material located above the surface of the ceramic base body, so that the material can be filled into the through-holes 10 particularly easily beyond the surface of the base body.
- Metal pastes of the compositions Ag90PdlO, Ag80Pd20, Ag70Pd30 and Ag60Pd40, for example, can be used as the electrically conductive material depending on the sintering temperature required (proportions in percent by weight).
- FIG. IC shows a cross section through a base body of an electrical component after method step D) of the method according to the invention.
- the ceramic green body was sintered, for example, at temperatures between 1000 ° C. and 1200 ° C. for two to eight hours.
- the electrically conductive material in the through-bores 10, the metal paste already mentioned above, was also hardened or co-sintered.
- the template 5, which consists of organic polymers, was evaporated at these temperatures by means of carbonization. Areas of the fillings 15 projecting over the surface of the base body remain, and these protruding areas can be wetted with solder particularly easily, so that the solder balls can be produced particularly easily on the surfaces 15A of the fillings.
