Abstract
Briefly stated, the present invention provides a vertical current flow semiconductor device (17). The vertical current flow semiconductor device (17) includes a semiconductor substrate (12) having an intermediate conductor layer (16) on a surface of the substrate (12). An active layer (11) that is used for forming active elements (20, 21, 22, 23) of the vertical current flow semiconductor device (17) is on the intermediate conductor layer (16). The intermediate conductor layer (16) forms an ohmic contact with the active layer (11).
