CONSTITUTION:In an Si epitaxial growth equipment, an amorphous silicon (a-Si) layer 4 whose film thickness is less than or equal to 500Angstrom  is deposited on a magnesia spinel at a substrate 1 temperature in the range from room temperature to 550 deg.C. In the equipment, this layer is subjected to solid growth at a substrate 1 temperature in the range from 500-800 deg.C, and seed crystal 5 is formed. The substrate 1 temperature is again reduced in the range from room temperature to 550 deg.C, and an a-Si layer 6 whose film thickness is from 0.2-0.6mum is deposited. When solid growth is performed in H2 gas atmosphere at a temperature less than or equal to 1000 deg.C, a single crystal Si layer 7 is formed on a magnesia spinel film 3. Thereby, the mixing of Al and Mg into the seed crystal 5 can be reduced.
