摘要: A method of manufacturing an epitaxial wafer, including a silicon substrate having a surface sliced from single-crystalline silicon and a silicon epitaxial layer deposited on the surface of the silicon substrate, includes an oxygen concentration controlling heat treatment process in which a heat treatment of the epitaxial layer is performed under a non-oxidizing atmosphere after the epitaxial growth such that an oxygen concentration of the surface of the silicon epitaxial layer is set to 1.0×1017 to 12×1017 atoms/cm3 (ASTM F-121, 1979).
