摘要： Wettability of a PBN material surface with respect to a metal is improved to expand use applications. Hydrogen ions are implanted into a surface of a silicon substrate 10 to form an ion implanted region 11 at a predetermined depth near a surface of the silicon substrate 10, and a plasma treatment or an ozone treatment is performed with respect to a main surface of the silicon substrate 10 for the purpose of surface cleaning or surface activation. The main surfaces of the silicon substrate 10 and a PBN substrate 20 subjected to the surface treatment are appressed against each other to be bonded at a room temperature, and an external impact shock is given to the bonded substrate to mechanically delaminate a silicon film 12 from a bulk 13 of the silicon substrate to be transferred. An obtained PBN composite substrate 30 is diced to form a chip having a desired size, and a refractory metal is metallized on the silicon film 12 side to be connected with a wiring material.

摘要： Hydrogen ions are implanted to a surface (main surface) of the single crystal Si substrate 10 at a dosage of 1.5×1017 atoms/cm2 or higher to form the hydrogen ion implanted layer (ion-implanted damage layer) 11. As a result of the hydrogen ion implantation, the hydrogen ion implanted boundary 12 is formed. The single crystal Si substrate 10 and the low melting glass substrate 20 are bonded together. The bonded substrate is heated at relatively low temperature, 120° C. or higher and 250° C. or lower (below a melting point of the support substrate). Further, an external shock is applied to delaminate the Si crystal film along the hydrogen ion implanted boundary 12 of the single crystal Si substrate 10 out of the heat-treated bonded substrate. Then, the surface of the resultant silicon thin film 13 is polished to remove a damaged portion, so that a semiconductor substrate can be fabricated. There can be provided a semiconductor substrate in which a high-quality silicon thin film is transferred onto a substrate made of a low melting point material.

摘要： A heating plate having a smooth surface is placed on a hot plate which constitutes a heating section, and the smooth surface of the heating plate is closely adhered on the rear surface of a single-crystal Si substrate bonded to a transparent insulating substrate. The temperature of the heating plate is kept at 200° C. or higher but not higher than 350° C. When the rear surface of the single-crystal Si substrate bonded to the insulating substrate is closely adhered on the heating plate, the single-crystal Si substrate is heated by thermal conduction, and a temperature difference is generated between the single-crystal Si substrate and the transparent insulating substrate. A large stress is generated between the both substrates due to rapid expansion of the single-crystal Si substrate, thus separation takes place at a hydrogen ion-implanted interface.

摘要： A silicon layer having a conductivity type opposite to that of a bulk is provided on the surface of a silicon substrate and hydrogen ions are implanted to a predetermined depth into the surface region of the silicon substrate through the silicon layer to form a hydrogen ion-implanted layer. Then, an n-type germanium-based crystal layer whose conductivity type is opposite to that of the silicon layer and a p-type germanium-based crystal layer whose conductivity type is opposite to that of the germanium-based crystal layer are successively vapor-phase grown to provide a germanium-based crystal. The surface of the germanium-based crystal layer and the surface of the supporting substrate are bonded together. In this state, impact is applied externally to separate a silicon crystal from the silicon substrate along the hydrogen ion-implanted layer, thereby transferring a laminated structure composed of the germanium-based crystal and the silicon crystal onto the supporting substrate.
