Abstract:
A power semiconductor device of the present invention includes: a semiconductor base body which has a super junction structure formed of a plurality of first conductive-type columnar regions and a plurality of second conductive-type columnar regions; a plurality of trenches; gate insulation films; gate electrodes; an interlayer insulation film; contact holes formed such that two or more contact holes are formed between two trenches disposed adjacently to each other; metal plugs formed by filling the inside of the contact holes with metal; and an electrode, wherein a first conductive-type high concentration diffusion region is formed only between the trench and the metal plug disposed closest to the trench between each two trenches disposed adjacently to each other. According to the power semiconductor device of the present invention, it is possible to provide a power semiconductor device which satisfies a demand for reduction in cost and downsizing of electronic equipment, and has a large breakdown strength.

Claim (Index 5):
The power semiconductor device according to  claim 1 , wherein a distance between two gate electrodes disposed adjacently to each other is 2.5 \u03bcm or more.
