摘要： The present invention provides a thermally conductive silicone composition which contains: an organopolysiloxane which is a reaction product obtained by reacting (A) an organopolysiloxane having an alkenyl group bonded to a silicon atom and (B) an organohydrogen polysiloxane with each other at a molar ratio of the Si—H group in the component (B) to the alkenyl group bonded to a silicon atom in the component (A), namely (Si—H/Si-Vi) of 2.0-9.0; (C) an inorganic filler which is selected from among metal oxides and metal nitrides, and which has an average particle diameter of 3 μm or less; and (D) a thermally conductive inorganic filler which has an average particle diameter of 5 μm or more. This thermally conductive silicone composition has excellent displacement resistance and excellent coatability by setting the total of the component (C) and the component (D) to 200-6,000 parts by mass relative to 100 parts by mass of the total of the component (A) and the component (B), and having an absolute viscosity at 25° C. of 100-800 Pa·s. The present invention also provides a method for producing this thermally conductive silicone composition.

摘要： A method of transferring a device layer in a SOI wafer obtained by stacking a Si layer, an insulator layer, and the device layer to a transfer substrate, includes a step of temporarily bonding a surface on which the device layer is formed of the SOI wafer to a supporting substrate using an adhesive for temporary bonding, a step of removing the Si layer of the SOI wafer until the insulator layer is exposed and obtaining a thinned device wafer, a step of coating only the transfer substrate with an adhesive for transfer and then bonding the insulator layer in the thinned device wafer to the transfer substrate via the adhesive for transfer, a step of thermally curing the adhesive for transfer under a load at the same time as or after bonding, a step of peeling off the supporting substrate, and a step of removing the adhesive.

摘要： A photomask blank is processed into a transmissive photomask for use in photolithography for forming a pattern on a recipient using exposure light. The photomask blank comprises a transparent substrate, a first film of a material which is etchable by chlorine/oxygen-based dry etching, and a second film of a silicon-containing material. The second film includes a layer having a refractive index n of at least 1.6 or an extinction coefficient k of at least 0.3 with respect to the wavelength of inspection light which is longer than the exposure light.

摘要： An outer blade cutting wheel is provided comprising an annular thin disc base and a blade section of bonded abrasive grains on the periphery of the base. Provided that an imaginary range is delineated by two imaginary planes extending parallel to the planar surfaces of the base and tangent to widthwise side portions of the blade section and two imaginary circumferences defined about the rotational axis and extending tangent to inner and outer perimeters of the blade section, the blade section occupies 10-40% by volume of the imaginary range minus the region of the base, and the widthwise side portions of the blade section have a dented shape relative to the imaginary planes. The cutting wheel is capable of cutoff machining at a high feed speed while maintaining a high accuracy and a low cutting load.
