摘要： A process for producing a semiconductor substrate, including the phases of implanting oxygen ions into a semiconductor silicon substrate through one surface thereof to form a high oxygen concentration layer in the semiconductor silicon substrate, and then heat-treating the semiconductor substrate to cause a chemical reaction to occur between the implanted oxygen ions and the silicon, thereby forming an insulating silicon oxide film in the semiconductor silicon substrate, wherein the heat treatment phase includes at least a heat treatment step using an atmosphere having an oxygen partial pressure of 5.times.10.sup.3 Pa or more.The process is advantageously used to produce a high quality SOI semiconductor substrate in which the number of the defects providing a path for current leakage is reduced, the buried oxide layer has an improved dielectric breakdown strength, the interface between the buried oxide film and the adjoining silicon layers has a small roughness, and the buried oxide film can be produced with a wider range of thickness.
