Method for Producing a Semiconductor Component with Insulated Semiconductor Mesas in a Semiconductor Body
Abstract:
A method for producing a semiconductor component is provided. The method includes providing a semiconductor body with a first surface and a second surface opposite to the first surface, etching an insulation trench from the first surface partially into the semiconductor body, forming a first insulation layer on one or more sidewalls of the insulation trench, processing the second surface by at least one of grinding, polishing and a CMP-process to expose the first insulation layer, and depositing on the processed second surface a second insulation layer which extends to the first insulation layer.
