Edge border used for high voltage semiconductor component has the site of the bend and sealing of equipotential lines applied using a voltage in an insulating region

摘要

Edge border comprises: a semiconductor body (1) of one conducting type with semiconducting regions (2,3) on an edge surface region bordering a first main surface; and a field plate (4) arranged on the edge surface region and the first main surface. The site of the bend and sealing of equipotential lines (9) is applied using a voltage in an insulating region (6). An Independent claim is also included for a process for the production of an insulating region in a semiconductor body. Preferred Features: The insulating region is an insulating region extending vertically from the first main surface into the semiconductor body.
