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.

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.

To obtain a semiconductor substrate having a high-quality Ge-based epitaxial film in a large area, a SiGe mixed crystal buffer layer and a Ge epitaxial film is grown on a main surface of a Si substrate 10. Although high-density defects are introduced in the Ge epitaxial film 11 from an interface between the Ge epitaxial film 11 and the Si substrate 10, the Ge epitaxial film is subjected to a heat treatment at a temperature of not less than 700° C. and not more than 900° C. to cause threading dislocations 12 to change into dislocation-loop defects 12′ near the interface between the Ge epitaxial film 11 and the Si substrate. A main surface of at least one of the Ge epitaxial film 11 with an ion implanted layer and a support substrate 20 is then subjected to a plasma treatment or ozone treatment for the purpose of surface cleaning, surface activation, and the like, after which the main surfaces of the Ge epitaxial film 11 and the support substrate 20 are appressed against and bonded to each other with their surfaces being determined as the joint surfaces. An external impact is then applied to the bonding interface, causing the Ge epitaxial film to be delaminated along a hydrogen ion implanted interface 13, thus obtaining a Ge thin film 14. A surface of the Ge thin film 14 is subsequently subjected to a final surface treatment (for example, CMP) to remove the damage caused by the hydrogen ion implantation, thus resulting in a GeOI substrate having the Ge thin film 14 on the surface thereof.

To lower a process temperature for an SOQ substrate manufacturing process to reduce the degree of surface roughness of an SOQ film and provide a high-quality SOQ substrate.Hydrogen ions are implanted to a surface of a single crystal Si substrate 10 through an oxide film 11 to uniformly form an ion implanted layer 12 at a predetermined depth (average ion implantation depth L) from the surface of the single crystal Si substrate 10, and a bonding surface of the substrate undergoes a plasma treatment or an ozone treatment. An external shock is applied onto the single crystal Si substrate 10 and quartz substrate 20, which are bonded together, to mechanically delaminate a silicon film 13 from a single crystal silicon bulk 14. In this way, the SOQ film 13 is formed on the quartz substrate 20 through the oxide film 11. To further smooth the SOQ film surface, hydrogen heat treatment is performed at a temperature of 1000° C. or less below a quartz glass transition point. When measuring surface roughness of an SOQ film after performing hydrogen heat treatment on a sample having surface roughness of about 5 nm in terms of RMS average value immediately after delamination, a satisfactory measurement result of 0.3 nm or less in terms of RMS average value was obtained.

摘要:
A radio apparatus forming a radio network system calculates a calculated distance, based on a tentative self-position and tentative positions of a plurality of radio apparatuses existing in the vicinity. The radio apparatus successively and autonomously corrects the tentative self-position so that the calculated distance comes closer to the measured distance, relying more heavily on the calculated distance than the measured distance between itself and each of the plurality of radio apparatuses, and determines the position of itself. Other radio apparatuses also successively correct the tentative self-positions by the same method as the radio apparatus, and determine the positions of themselves.
摘要:
A mast cell surface antigen, DNA thereof and an antibody against the antigen are provided. The amino acid sequence of this mast cell surface antigen is the translation of the coding region of its DNA. The base sequence of this DNA has been clarified in the following manner. Namely, mast cells obtained by incubating cord blood monocular cells are co-incubated with primary culture of fibroblasts to give connective tissue type mast cells (MC-TC). Then mRNA is extracted from this MC-TC cell extraction and a cDNA library is constructed therefrom. Immunological screening is carried out with the use of anti-MC-TC antiserum and the base sequence of the positive clone thus obtained is identified. Owing to the clarification of the amino acid sequence of this mast cell antigen, it becomes possible to reveal the role of mast cells in the pathology of allergic diseases and thus an antibody against mast cells can be easily obtained.
