Abstract:
1. A gate-resistor structure on a semiconductor body, the semiconductor body comprising a gate electrode of a first conductivity type or a second conductivity type, the gate electrode comprising a top surface, the gate structure comprises: a first semiconductor region of the first conductivity type, extending from the top surface into the gate electrode in a vertical direction; a second semiconductor region of the second conductivity type, arranged in the gate electrode and forming a p-n junction with the first semiconductor region, the second semiconductor region being arranged below the first semiconductor region in a vertical direction; an insulating layer arranged to insulate the first semiconductor region from the surrounding gate electrode; a contact layer arranged on the top surface, covering the first semiconductor region to electrically connect the first semiconductor region and additionally covering portions of the top surface beside the first semiconductor region in a horizontal direction.
