Latest Patents
Kiyokazu Nakagawa holds a patent for a semiconductor device featuring a doping multilayer structure. This invention includes a multilayer semiconductor structure that alternates between heavily doped p- (or n-) type semiconductor layers and lightly doped n- (or p-) type semiconductor layers. The design allows for the confinement of holes (or electrons) within a narrow layer, resembling a two-dimensional gas. This configuration enables high mobility despite a high carrier concentration. The electrical conductivity of the multilayer semiconductor structure surpasses that of bulk semiconductors. Remarkably, very high conductivity can be achieved by forming each layer with a thickness ranging from 10 .ANG. to 1000 .ANG., with a preference for 50 .ANG. to 500 .ANG. Additionally, the impurity concentration ratio between the heavily doped layer and the lightly doped layer is not less than one order of magnitude.
