Abstract:
A trench gate structure vertical MOSFET includes a silicon carbide substrate of a first conductivity type, a first semiconductor layer of the first conductivity type, a second semiconductor layer of a second conductivity type, first semiconductor regions of the first conductivity type, a trench, a gate electrode, an interlayer insulating film, a barrier layer, a contact electrode, a first electrode, and a second electrode. The barrier layer includes a layer made of TiN, and the thickness of the TiN layer is 10 to 80 nm. The interlayer insulating film is a laminate film of non-doped silicate glass and borophosphosilicate glass.

Claim (Index 13):
The method of manufacturing the silicon carbide semiconductor device according to  claim 9 , wherein in the interlayer insulating film, the layer of non-doped silicate glass is under the layer of borophosphosilicate glass.
