Abstract

See full text

According to an embodiment of a semiconductor device, the semiconductor device includes: a first active cell area comprising a first plurality of parallel gate trenches; a second active cell area comprising a second plurality of parallel gate trenches; and a metallization layer above the first and the second active cell areas. The metallization layer includes: a first part contacting a semiconductor mesa region between the plurality of parallel gate trenches in the first and the second active cell areas; and a second part surrounding the first part. The second part of the metallization layer contacts the first plurality of gate trenches along a first direction and the second plurality of gate trenches along a second direction different from the first direction.
