Abstract:
A semiconductor device is provided, including: a semiconductor substrate having an active area and an edge termination region; an upper electrode; an insulating film provided between the semiconductor substrate and the upper electrode and having a contact hole; a first conductivity-type drift region; a second conductivity-type base region; a second conductivity-type well region; and a second conductivity-type extension region formed extending in a direction toward the well region from the base region and separated from the upper electrode by the insulating film, wherein a sum of a first distance from an end portion of the contact hole closer to the well region to an end portion of the extension region closer to the well region and a second distance from the end portion of the extension region closer to the well region to the well region is smaller than a thickness of the semiconductor substrate in the active area.

Claim (Index 9):
The semiconductor device according to  claim 8 , wherein the end portion of the cathode region closer to the edge termination region is arranged closer to the active area than the end portion of the extension region closer to the well region.
