Abstract

A P-type compound semiconductor layer doped with carbon is formed on a semi-insulating substrate by placing the substrate in a reactor, and carrying out vapor-phase epitaxy by feeding and thermally decomposing vapors of an organic metal compound including a methyl radical, arsine, and an alkyl compound of arsenic substantially simultaneously into the reactor so that a C-doped P-type compound semiconductor is deposited on the substrate.
