Abstract
A semiconductor device includes: a cell region; a terminal region; a lower semiconductor layer; a intermediate semiconductor layer on the lower semiconductor layer including a super junction structure; a terminal upper semiconductor layer on the intermediate semiconductor layer; a terminal contact semiconductor region on a surface portion of the terminal upper semiconductor layer adjacent to the cell region; an insulation layer on the terminal upper semiconductor layer having a first part adjacent to the cell region with a small thickness and a second part adjacent to the first part with a large thickness; and a conductive layer in the cell region and a part of the terminal region, the conductive layer extending from the cell region to the part of the terminal region beyond the first part of the insulation layer.
