Abstract:
An IGBT includes current sense cell having a sensing area for sensing a current flowing an active area and an extraction area for extracting a hole current. The extraction area around the sensing area, has a portion in a gate trench is not in contact with the emitter region, and a p-type well region provided deeper than the first trench and having a high impurity concentration. An area of the extraction area is four times or more and 10,000 times or less an area of the sensing area.

Claim (Index 5):
The insulated gate bipolar transistor of  claim 4 , wherein, the dummy electrode is electrically connected to the emitter potential.
