    摘要: A method of producing an SOI substrate having a single-crystal silicon layer on a buried oxide layer in an electrically insulating state from the substrate by implanting oxygen ions into a single crystal silicon substrate and practicing an anneal processing in an inert gas atmosphere at high temperatures to form the buried oxide layer. After the anneal processing in which the thickness of the buried oxide layer becomes a theoretical value in conformity with the thickness of the buried oxide layer formed by the implanted oxygen, the oxidation processing of the substrate is carried out in a high temperature oxygen atmosphere.
