Abstract
An IGBT is specified which can be produced in a simple manner yet can be turned on homogeneously. For this purpose, gate fingers are dispensed with and the gate current in the IGBT-Chip is forwarded, proceeding from the gate terminal, directly via the polysilicon layers of the gate electrodes to the IGBT standard cells.
