Abstract:
A semiconductor device which includes a semiconductor layer, a first electrode, a second electrode, first trenches, a second trench surrounding the first trenches, a gate electrode and a first field plate electrode in the first trenches, a first insulating layer including a first portion p having a first film thickness, a second portion having a second film thickness thicker than the first film thickness, and a third portion having a third film thickness thicker than the second film thickness, a second field plate electrode in the second trench, a second insulating layer in the second trench. The semiconductor layer includes a first semiconductor region having a first conductivity type, a second semiconductor region having a second conductivity type, and a third semiconductor region having the second conductivity type.

Claim (Index 11):
The semiconductor device according to  claim 1 , further comprising:\n a plurality of third trenches in the semiconductor layer, extending longitudinally in the first direction, and having a length along the first direction that is shorter than a length of the plurality of first trenches along the first direction; and a fourth trench in the semiconductor layer, extending longitudinally in the first direction, and disposed between the plurality of first trenches and the plurality of third trenches, wherein the second trench surrounds the plurality of first trenches, the plurality of third trenches, and the fourth trench within the plane substantially parallel to the first surface, a distance between an end portion of the fourth trench and the second trench is less than a distance between the end portion of each first trench of the plurality of first trenches and the second trench and also less than a distance between an end portion of each third trench of the plurality of third trenches and the second trench.
