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 2):
The semiconductor device according to  claim 1 , wherein\n the well region has a plurality of well tooth portions forming a first comb portion, the drift region has a plurality of drift tooth portions forming a second comb portion, two well tooth portions of the plurality of well tooth portions sandwich one drift tooth portion of the plurality of drift tooth portions, and a pn junction of each of the plurality of well tooth portions and each of the plurality of drift tooth portions extends from the main surface toward the bottom surface of the isolation trench along the lateral surface of the isolation trench on the side of the source region.
