    摘要： A trench MOS type SiC semiconductor device includes a first conductivity semiconductor substrate, a first conductivity drift layer on the substrate, a second conductivity base layer on the drift layer, a first conductivity source layer on the base layer, a stripe shaped trench reaching from the surface of the source layer to the drift layer and having a gate electrode via a gate oxide film, a second conductivity layer on the bottom of the trench, and a second conductivity type region thereon on across-the-width side walls of at least one end of the trench, electrically coupling the second conductivity layer with the base layer. The device allows a low on-resistance without newly forming an electrode connected to the second conductivity layer even in the case of a device in which the second conductivity layer has to be grounded.

    摘要： Stress is exerted to the SiC crystal in the region, in which the carriers of a SiC semiconductor device flow, to change the crystal lattice intervals of the SiC crystal. Since the degeneration of the conduction bands in the bottoms thereof is dissolved, since the inter-band scattering is prevented from causing, and since the effective electron mass is reduced due to the crystal lattice interval change, the carrier mobility in the SiC crystal is improved, the resistance of the SiC crystal is reduced and, therefore, the on-resistance of the SiC semiconductor device is reduced.
