Abstract

A semiconductor substrate comprises a foundation, a semiconductor monocrystalline film formed on the foundation, and a high-melting-point metal film or a high-melting-point metal alloy film disposed in at least part of a region between the semiconductor monocrystalline film and the foundation. The high-melting-point metal film disposed below the semiconductor monocrystalline film can be utilized as a conductor in a semiconductor device.
