Field: Semiconductors (Electrical engineering)
Classification: CPC H | IPC H

Claim 6:
7. A method, comprising:
providing a semiconductor body having a first side and a second side, wherein the second side is opposite the first side across a thickness of the semiconductor body;
forming a high voltage semiconductor device on the first side of the semiconductor body;
forming a contiguous electrode on or in a dielectric layer on the second side of the semiconductor body, wherein the contiguous electrode is insulated from the semiconductor body by the dielectric layer, the contiguous electrode is directly opposite the high voltage semiconductor device, and the contiguous electrode has sidewalls that define a gap that is directly opposite the high voltage semiconductor device;
a first portion of the contiguous electrode is on a first side of the gap; and
a second portion of the contiguous electrode is on a second side of the gap, opposite the first side of the gap.
