Abstract:
A method of electrically connecting insulated-gate bipolar transistor chips mounted on an integrated-circuit wafer (10), said method comprising the step of soldering the collector, emitter and gate-control electrodes (26, 28) to corresponding connection locations (14, 16) of the chips, said method further comprising the steps of:choosing the emitter and gate-control electrodes (26, 28) to be a set of connection pads;making at least some of the emitter electrodes (26) in a single piece in the form of a plate (20) of electrically conducting material, which, on one of its large faces, has protruding parts which form a single piece with the plate (20) and which define the connection pads; and soldering the connection pads to the corresponding connection locations.
