摘要:
A semiconductor device with switch electrode and gate electrode and a method for switching a semiconductor device. One embodiment provides a semiconductor substrate with an emitter region, a drift region, a body region and a source region. The drift region is formed between the emitter and the body region while the body region is formed between the drift and the source region. A first trench structure extends from the source region at least partially into the drift region. The first trench structure includes a gate electrode arranged next to the body region and a switch electrode arranged in portions next to the drift region, wherein the switch and gate electrodes are electrically insulated from each other in the trench structure. A first gate driver is electrically connected to the gate electrode while a second gate driver is electrically connected to the switch gate.
