  • METHOD OF MANUFACTURING SOI SUBSTRATE
    Publication number: 20110244652
    Abstract: An object of the present invention is to provide an SOI substrate including a semiconductor layer which is efficiently planarized. A method for manufacturing an SOI substrate includes a step of irradiating a bond substrate with an accelerated ion to form an embrittlement region; a step of bonding the bond substrate and the base substrate with an insulating layer positioned therebetween; a step of splitting the bond substrate at the embrittlement region to leave a semiconductor layer bonded to the base substrate; a step of disposing the semiconductor layer in front of a semiconductor target containing the same semiconductor material as the semiconductor layer; and a step of alternately irradiating the surface of the semiconductor layer and the semiconductor target with a rare gas ion, so that the surface of the semiconductor layer is planarized.
