Abstract:
A semiconductor device includes a drain layer, a drift layer, a base region, a source region, trenches, base contact region, gate regions, and field plate electrodes. The drain layer extends in a first and a second direction. The drift layer is on the drain layer. The base region is on the drift layer. The source region is on the base region. The trenches are in an array and each trench reaches the drift layer from the source region. The base contact region is along the second direction in a region in which the trenches do not contiguously exist along the second direction and electrically connects the source region to the base region. Each gate regions is along an inner wall of the trenches. Each field plate electrodes is in an inside of the gate regions and is longer than the gate regions in the third direction.

Claim (Index 2):
The semiconductor device according to  claim 1 , further comprising:\n a first metal layer being connected to the base contact region and the source region via a first source contact, and being connected to corresponding one of the field plate electrodes via a second source contact, a second metal layer being insulating via the insulating film from the first metal layer, and being connected to corresponding one of the gate regions via a gate contact; and a third metal layer formed to be layered in the third direction of the first metal layer and the second metal layer, to be connected to the first metal layer and to be insulated from the second metal layer via the insulating film.
