Abstract:
In an edge termination region, in a carrier drawing region between an active region and a gate runner part, a p + -type contact region is provided in a surface region of a p-type well region. In the carrier drawing region, in second contact holes formed an interlayer insulating film, a contact plug is embedded in each via the barrier metal, and contacts of the p + -type contact region and the barrier metal at an emitter electric potential are formed. The contacts of the carrier drawing region are disposed in a striped layout extending along an outer periphery of the active region; the contacts surround the active region. A contact resistance of the contacts of the carrier drawing region is higher than a contact resistance of a contact (emitter contact) of a MOS gate.

Claim (Index 14):
The semiconductor device according to  claim 1 , further comprising\n an eighth semiconductor region of the first conductivity type between the first semiconductor region and the fifth semiconductor region, the eighth semiconductor region having an impurity concentration that is higher than an impurity concentration of the fifth semiconductor region.
