Abstract:
A first comb portion of an n-type well region and a second comb portion of a p −  drift region mesh with each other in plan view. A pn junction of the n-type well region and the p −  drift region thus has a zigzag shape in plan view. The pn junction formed of the n-type well region and the p −  drift region extends from a main surface toward a bottom surface of the isolation trench along a source-side wall surface of an isolation trench.

Claim (Index 6):
The semiconductor device according to  claim 2 , further comprising an impurity region of second conductivity type which is disposed opposite to the main surface with respect to the well region and the drift region,\n wherein a lower surface of the well region is not in contact with the drift region and is in contact with the impurity region.
