(Claim 1) Sagawa teaches a multilayered semiconductor device comprising:
a substrate (2, SiC) comprising silicon carbide (SiC) [Detailed Description of Embodiments of the Present Disclosure];
an epitaxial transition layer (3)) comprising a first epitaxial oxide material ((In .sub.0.1 Ga .sub.0.9 ) .sub.2 O .sub.3) or SiC, wherein the epitaxial transition layer is on the substrate;
one or more epitaxial active regions (4) comprising one or more second epitaxial oxide materials ((In .sub.0.1 Ga .sub.0.9 ) .sub.2 O .sub.3) formed on the epitaxial transition layer (3);
a metal layer (11) above the one or more epitaxial active regions,
wherein the metal layer comprises one or more electrical contacts; and
the multilayered semiconductor device comprises one of a metal-oxide field-effect transistor, a vertical conduction metal-oxide field-effect transistor, a lateral field-effect transistor, a metal-semiconductor field-effect transistor, a bipolar junction transistor, a junction field-effect transistor, a metal-insulator-semiconductor device, a PN device, a PNP device, an NPN device, or an insulated-gate bipolar transistor [Detailed Description of Embodiments of the Present Disclosure].
