Abstract
A semiconductor device includes a substrate having a recess, a gate electrode in the recess in the substrate, and a source electrode and a drain electrode disposed on opposite sides of the gate electrode. An insulating film is on at least on a surface of the gate electrode and a portion in the recess, other than where the gate electrode is located, and a shield electrode connected to the source electrode is located on a portion of the insulating film between the gate electrode and the drain electrode.
