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 4):
The insulated gate bipolar transistor of  claim 3 , wherein\n in the first extraction area, a tip of the second trench, which is facing to the interspace in parallel with the first trench, recedes by a certain distance from a tip of the first trench toward an opposite direction to the second extraction area, and tips of both of the first trenches provided in the first and second extraction areas, which faces the interspace, are electrically connected by a strip-shaped gate runner.
