An electronic circuit mounting arrangement includes heat-conducting, electrically insulating and/or conducting pastes (14, 30) as well as flexible conductor plates (16, 28). The utilization and application of these elements make it possible to increase the packing density of the components (22, 32) also in the field of the high-power circuit arrangements. It further provides for a substantial rationalization in the connection technique for an optimization in the means of the contacting procedure. The economic manufacturing, accompanied by a destruction-free partial demountability, permits based on the use of pastes and foils the further mounting of electronic circuit arrangements resulting in an increased circuit density in one circuit unit.

Electronic circuit arrangement

A system is disclosed for the production of a number of disk-shaped semiconductor bodies from a large face contacted semiconductor starting chip, which is attached to a carrier plate, where in several steps simultaneous treatment of all semiconductor bodies in the set is obtained and where in further steps an individual treatment occurs. This method is improved by connecting the semiconductor component bodies generated by dicing of the starting chip to a foil-like structure with the aid of a silicone rubber with particular properties. A device for supporting the structure and for further treatment of the therein mechanically stable supported semiconductor device element is attached with silicon rubber to the structure before detaching of the starting disk. This support means is detached jointly with the structure from the carrier plate. The structure of semiconductor component elements and silicone rubber attached to the support means is subjected to further processing steps including at least some measurements, and thereupon the semiconductor components elements are separated. A defined edge profile is generated at the sections forming semiconductor component elements, for example by etching or sandblasting within the process of dicing the starting semiconductor chip.
