Abstract:
First and second cell trench structures extend from a first surface into a semiconductor substrate. The first cell trench structure includes a first buried electrode and a first insulator layer between the first buried electrode and a semiconductor mesa separating the first and second cell trench structures. A capping layer covers the first surface. The capping layer is patterned to form an opening having a minimum width larger than a thickness of the first insulator layer. The opening exposes a first vertical section of the first insulator layer at the first surface. An exposed portion of the first insulator layer is removed to form a recess between the semiconductor mesa and the first buried electrode. A contact structure is in the opening and the recess. The contact structure electrically connects both a buried zone in the semiconductor mesa and the first buried electrode and allows for narrower semiconductor mesa width.

Claim (Index 7):
The semiconductor device of  claim 1 , further comprising a capping layer formed on a first main surface of the semiconductor substrate into which the plurality of first cell trench structures and the plurality of second cell trench structures extend, wherein the electrically conductive material disposed in each recess formed in the first insulator layer extends through openings in the capping layer to form part of an overlying contact structure.
