Patent JP-H0377353-A (JP)
Title: Compound semiconductor substrate
Inventor: MORI HIDEFUMI
IPC: H01L21/86
Filed: 1989-08-21
Abstract: PURPOSE:To form a good-quality III-V semiconductor crystal on a sapphire substrate by a method wherein a single-crystal germanium film whose coefficient of thermal expansion is close to that of a sapphire is arranged as a compound semiconductor crystal film between the crystal and the sapphire substrate. CONSTITUTION:Germanium 2 is grown on a sapphire substrate 3 having a substrate orientation of 1012. For this operation, the sapphire substrate 3 is put into a growth apparatus; it is first heated to 1400 deg.C; the substrate surface is cleaned. Then, a substrate temperature is kept at 800 deg.C, GeH4 is introduced into the growth apparatus; the germanium 2 is grown to 1mum thickness. Then, a GaAs layer is grown on the substrate by an ordinary MOCVD method. Concretely, a germanium layer is grown; after that, temperature is lowered to 400 deg.C; a GaAs film is grown to be thin, e.g. in 10mum; then, the substrate temperature is raised to 600 deg.C, the GaAs film is grown to 2mum thickness. Since a coefficient of thermal expansion of the germanium grown on the sapphire substrate is close to that of a sapphire, a crystal of the germanium is not destroyed by stress due to a difference in the coefficient of thermal expansion during a process to lower the substrate temperature down to room temperature after a growth operation; as a result, a product whose crystallinity is good can be obtained.
