Abstract

A semiconductor component comprises a semiconductor body with at least one protective trench in the semiconductor body. An insulation layer is situated at least at the bottom of the protective trench. An electrically conductive layer having a thickness D is formed on the insulation layer in the protective trench, wherein the electrically conductive layer only partly fills the protective trench.
