摘要： PROBLEM TO BE SOLVED: To provide a substrate for semiconductor element provided, on the surface thereof, with a silicon carbide epitaxial film having a high crystallinity and a low defect density.
SOLUTION: The substrate 10 for a semiconductor element is provided, on the surface of the substrate 11, with a first thin film layer 12, a second thin film layer 13 and a surface thin film layer 14 in this order. The substrate 11 is a crystal substrate of Al
2 O
3 , the first thin film layer 12 is a thin film of AlN, and the second thin film layer 13 is a thin film of TiC. The surface thin film layer 14 is a heteroepitaxial film produced through heteroepitaxial growth of 4H-Si of hexagonal system. TiC of the second thin film layer 13 exhibits higher crystal lattice matching to 4H-SiC of the surface thin film layer 14 (heteroepitaxial film) than to AlN of the first thin film layer 12. Consequently, crystal matching is enhanced between TiC and 4H-SiC when the surface thin film layer 14 is formed on the second thin film layer 13 through heteroepitaxial growth of 4H-SiC.
