摘要: A method of growing a crystal (for example, a GaN system compound semiconductor crystal) on a substrate at least includes forming a first crystalline layer (a GaN system buffer layer), forming a second crystalline layer (a GaN system intermediate layer) and forming a third crystalline layer (a GaN system thick film layer). The three crystalline layers are respectively reared on conditions different from one another.
