Claim:
1. A semiconductor device, comprising: a first semiconductor region of a first conductivity type including a first region and a second region surrounding the first region; a second semiconductor region of a second conductivity type on the first region of the first semiconductor region; a third semiconductor region of the first conductivity type on a portion of the second semiconductor region; a conductive layer including: a gate electrode disposed above the first conductive portion in the third direction, the first insulating portion being between the gate electrode and the first conductive portion in the third direction, the gate electrode facing the second semiconductor region with a second insulating portion being between the gate electrode and the second semiconductor region; and a first electrode above the conductive layer in the third direction and electrically connected to the third semiconductor region and the conductive layer, the second conductive portion electrically connecting the first electrode to the third conductive portion.
