Patent ID: 8772132

Claim:
A method of manufacturing a laminated wafer by forming a silicon film on a surface of a transparent insulating substrate, the method comprising the steps in the following order of: implanting ions from a surface of a silicon wafer or a silicon wafer covered with an oxide film to form an ion implantation interface; applying a surface activation treatment to the surface of the insulating substrate and/of to the surface of the silicon wafer or the silicon wafer covered with the oxide film to which the ions have been implanted; bonding the surface, to which the ions have been implanted, of the silicon wafer or the silicon wafer covered with the oxide film and the surface of the insulating substrate in an atmosphere of temperature exceeding 50° C. and lower than 300° C.; applying a heat treatment at 200° C. to 350° C.; and applying a mechanical impact to the ion implantation interface so that a silicon film is transferred to form the silicon film layer on the insulating substrate wherein the insulating substrate is selected from quartz wafer, sapphire wafer, alumina wafer or glass wafer.
