Abstract
Disclosed is a transistor device and a method for producing a transistor device. The transistor device includes: a source region, a drift region, and a body region arranged between the source region and the drift region; a gate electrode adjacent the body region and dielectrically insulated from the body region by a gate dielectric; and a field electrode adjacent the drift region and dielectrically insulated from the drift region by a field electrode dielectric. The field electrode includes first and second layers.
