    摘要: In a manufacturing method of manufacturing a silicon on insulator (SOI) wafer, a single crystal silicon whose surface is an N region on an outer side of an OSF region, is grown and sliced to fabricate an N region single crystal silicon. An ion injection layer is formed within the N region single crystal silicon wafer by injecting a hydrogen ion or a rare gas ion from a surface of the N region single crystal silicon wafer; the ion injection surface of the N region single crystal silicon wafer and/or a surface of the transparent insulation substrate is processed using plasma and/or ozone. The ion injection surface is bonded to the surface of the transparent insulation substrate by bringing them into close contact with each other at room temperature. An SOI layer is formed by mechanically peeling the single crystal silicon wafer.

    摘要: Proposed is an improvement in the process for the preparation of an SOI wafer comprising the steps of: forming an oxidized surface film on the mirror-polished surface of a first mirror-polished semiconductor silicon wafer as the base wafer; forming a doped layer with a dopant in a high concentration on the mirror-polished surface of a second mirror-polished semiconductor silicon wafer as the bond wafer; bringing the base wafer and the bond wafer into contact each with the other at the oxidized surface film and the doped layer; and subjecting the thus contacted semiconductor silicon wafers to a heat treatment to effect integral bonding thereof into a precursor of an SOI wafer. The improvement of the invention is accomplished by polishing the surface of the doped layer on the bond wafer before the base wafer and the bond wafer are joined by contacting at the oxidized surface film and the doped layer so that a great improvement can be obtained in the bonding strength between layers.
