Abstract:
A semiconductor device includes first to fourth semiconductor regions, and first and second electrodes. The second semiconductor region is selectively disposed in a surface layer of one main surface of the first semiconductor region. The first electrode is in contact with a contact region of the second semiconductor region. The third semiconductor region is disposed in a surface layer on another main surface of the first semiconductor region, and having an impurity concentration higher than that of the first semiconductor region. The second electrode is in contact with the third semiconductor region. The fourth semiconductor region of the second conductivity type is disposed in the first semiconductor region, and disposed closer to the one main surface than the third semiconductor region. The fourth semiconductor region is disposed at least within the contact region in a plan view.

Claim (Index 4):
The semiconductor device according to  claim 1 , wherein\n the fourth semiconductor region includes\n a plurality of first fourth semiconductor regions, each of which is disposed an inside of the contact region, and \n a plurality of second fourth semiconductor regions, each of which is disposed the outside of the contact region, \n the semiconductor device includes first to fourth areas in the plan view,\n the first area being defined as an outside of the contact region from the outermost periphery of the contact region and having an area size A 20 , \n the second area being defined as a total area of surfaces of the second fourth semiconductor regions and having an area size A 21  in total, \n the third area being defined as an inside of the contact region from the outermost periphery of the contact region and having an area size A 10 , \n the fourth area being defined as a total area of surfaces of the first fourth semiconductor regions and having an area size All in total, and the area sizes A 20 , A 21 , A 10  and A 11  satisfy A 21 /A 20 <A 11 /A 10 .
