    摘要: A technique related to a bonded semiconductor substrate capable of reducing an interface resistance is provided. The semiconductor substrate comprises a single-crystalline SiC substrate and a polycrystalline SiC substrate. The single-crystalline SIC substrate and the polycrystalline SiC substrate are bonded. A bonded region of the single-crystalline SiC substrate and the polycrystalline SiC substrate contains 1×1021 (atoms/cm3) or more of particular atoms.
