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 8):
The semiconductor device according to  claim 1 , further comprising:\n a fourth semiconductor region of the semiconductor layer between the second semiconductor region and an end portion of the first semiconductor region, the fourth semiconductor region contacting the first semiconductor region and being of the first conductivity type with an impurity concentration that is lower than an impurity concentration of the first semiconductor region.
