Title: Production of epitaxial wafer
Inventor: TAKAI NORIHEI
IPC: C30B25/18
Filed: 1985-01-25
Abstract: PURPOSE:To control easily the concn. of impurities and to prevent the contamination of the device forming region by forming the diffusion layer of the same impurities as the impurities contained in an Si substrate, forming an oxide- coated film after specified treatment, polishing the one surface, and then forming an epitaxial layer having the same electric conductivity as the Si substrate. CONSTITUTION:Intrinsic gettering is applied to an Si substrate 1 of usual impurity content produced by the CZ method to form an oxide depositing neucleus 2 at the inside of the substrate 1. After the same impurities as the contained impurities are diffused at the surface and in the vicinity of the surface of the substrate 1 to form a diffusion layer 3, an oxide coated film (SiO2) 4 is formed on the surface of the substrate 1 by oxidation or the rear surface CVD method. The one surface is subsequently mirror-polished to remove the oxide film 4. An epitaxial layer 5 having the same electric conductivity as the substrate 1 having high resistivity is formed on the polished surface by the reduction with hydrogen or thermal decomposition, and the desired epitaxial wafer is produced.
