Abstract (en)

[origin: WO9944240A1] The invention relates to an IGBT (Insulated Gate Bipolar Transistor) which is simple to produce but still switches on homogeneously. To this end, the inventive transistor does not have any gate fingers and starting from the gate terminal, the gate current in the IGBT chip is transmitted directly to the IGBT unit cells via the polysilicon layers of the gate electrodes.
