Abstract:
1. A vapor-phase growth method for growing a silicon film on a surface of a substrate, the method comprising supplying a mixed material gas that includes a chlorosilane gas and a carrier gas to the surface of the substrate heated at 1200 to 1400° C. from a direction perpendicular to the surface, wherein a melting point of the substrate being higher than that of silicon, a supply rate of the chlorosilane gas is equal to or more than 200 μmol per minute per 1 cm the carrier gas includes a hydrogen gas and at least one or more gases selected from argon, xenon, krypton and neon, wherein the mixed material gas is supplied while the substrate is rotated at equal to or more than 1000 rpm.
