Claim:
1. A semiconductor device, comprising: a first semiconductor region of a first conductivity type; a first electrode extending in a first direction; a second electrode spaced from the first electrode and including: a third electrode spaced from the first electrode and the second electrode in the second direction; a first insulation region between the first semiconductor region and the second electrode; a second insulation region between the first semiconductor region and the first electrode and between the first semiconductor region and the third electrode; a second semiconductor region of a second conductivity type on the first semiconductor region and adjacent to the third electrode through the second insulation region; a third semiconductor region of the first conductivity type on the second semiconductor region; a fourth semiconductor region of the second conductivity type on the first semiconductor region and between, in the first direction, adjacent first portions of the second electrode; and a fourth electrode on the third semiconductor region and electrically connected to the second semiconductor region, the third semiconductor region, the fourth semiconductor region, the first electrode, and the second electrode.
