Abstract

Disclosed is a transistor device and a method for producing thereof. The transistor device includes at least one transistor cell, wherein the at least one transistor cell includes: a source region, a body region and a drift region in a semiconductor body; a gate electrode dielectrically insulated from the body region by a gate dielectric; a field electrode dielectrically insulated from the drift region by a field electrode dielectric; and a contact plug extending from a first surface of the semiconductor body to the field electrode and adjoining the source region and the body region.
