Abstract:
An insulated gate bipolar transistor (IGBT) comprising:at least one IGBT-Chip with a plurality of parallel-connected IGBT standard cells for each at least one IGBT-Chip; a first main terminal; a second main terminal; and at least one gate terminal; wherein the at least one gate terminal is directly electrically operatively connected to gate electrodes of the IGBT standard cells, the gate electrodes being formed by polysilicon layers electrically connected in parallel, wherein the maximal gate signal propagation distance from the at least one gate terminal within the polysilicon layers is at least approximately equal to {square root over (&tgr;/RÂ·c)} with R being the sheet resistance of the polysilicon layers, c being the metal oxide semiconductor (MOS) capacitance per area of the gate, and &tgr;=RGateÂ·Ctot being the characteristic switching time of the at least one IGBT-Chip, with RGate being the gate series resistance and Ctot being the total MOS capacitance of the at least one IGBT-Chip.
