Assignee: FUJI ELECTRIC CO., LTD.
Field: Semiconductors (Electrical engineering)
Classification: CPC H | IPC H

Claim 18:
19. A semiconductor device including a transistor region and a diode region in a semiconductor substrate, the semiconductor device comprising:
a gate runner portion that supplies a gate potential to the transistor region;
a well region of a first conductivity type provided below the gate runner portion;
an interlayer dielectric film provided above the semiconductor substrate;
one or more first contact portions provided in the interlayer dielectric film in the diode region and extending in a first direction such that, when seen from above, an end of the one or more first contact portions does not overlap the well region; and
one or more second contact portions provided in the interlayer dielectric film in the transistor region and extending in the first direction such that, when seen from above, an end of the one or more second contact portions overlaps the well region.
