Abstract
A semiconductor is disclosed that may include: a first drift region; a base region arranged on the first semiconductor layer; a source region arranged on the base region; a main electrode electrically connected to the source region; and a gate electrode structure that penetrates the source region and base region and reaches the first drift region, wherein the gate electrode structure comprises: a gate electrode; and an insulating material that insulates the gate electrode from the first drift region and the base region; and a field plate structure reaching the first drift region deeper than the gate electrode structure, wherein the field plate structure comprises: a field plate; a resistive part that electrically connects the main electrode to the field plate; and an insulating material that insulates the field plate and the resistive part section from the first drift region and the base region.
