Abstract:
A method of manufacturing a semiconductor device includes: etching a plurality of trenches to a first depth in a semiconductor substrate; doping a region of the semiconductor substrate surrounding a bottom of the trenches at the first depth to form a doped region in the semiconductor substrate; after the doped region is formed, etching the plurality of trenches deeper into the semiconductor substrate to a second depth greater than the first depth, adjacent ones of the trenches being separated from one another by a semiconductor mesa; and forming a body region above the doped region in the semiconductor mesas.

Claim (Index 4):
The method of  claim 1 , wherein etching the plurality of trenches to the first depth in the semiconductor substrate comprises:\n forming a structured trench etch hard mask on a first main surface of the semiconductor substrate; and etching the plurality of trenches to the first depth in the semiconductor substrate through openings in the structured trench etch hard mask.
