EPITAXIAL SILICON WAFER AND PRODUCTION METHOD THEREOF

摘要

Provided is an epitaxial silicon wafer in which the warping is reduced by rendering a cross-sectional form of a silicon wafer for epitaxial growth into an adequate form as compared with the conventional one. An epitaxial silicon wafer comprising a silicon wafer for epitaxial growth and an epitaxial layer is characterized in that the epitaxial layer is formed on a silicon wafer for epitaxial growth having a cross-sectional form satisfying a relation of a given expression.
