Abstract
A semiconductor device has emitter regions disposed in at least one cell region in a first inter-trench region, not disposed in a middle inter-trench region, and disposed in at least one cell region in the second inter-trench region. Each of the emitter regions is disposed at a position that is not in contact with first trenches but is in contact with two second trenches defining the corresponding cell region.
