    摘要: A polyurethane resin having a total concentration of the urethane group and the urea group of not less than 15% by weight is prepared by reacting a diisocyanate component (e.g., an aromatic diisocyanate) with a diol component (e.g., a C2-8alkylene glycol). The repeating unit of the polyurethane resin may contain a constitutive unit of an aromatic or alicyclic compound. The polyurethane resin may be shaped into a film for use as a gas barrier film. The film may be a gas barrier composite film composed of a base film layer and a resin layer at least comprising the polyurethane resin. The present invention provides a polyurethane resin excellent in gas barrier properties against water vapor, oxygen, aromatics, and others, and a film containing the same.

    摘要: A silicon wafer is thermal-annealed in an atmosphere to form new vacancies therein by thermal annealing and the atmosphere in the thermal annealing contains a nitride gas having a lower decomposition temperature than a decomposable temperature of N2 so that the thermal annealing is carried out at a lower temperature or for a short time to suppress generation of slip and to provide satisfactory surface roughness.

    摘要: Urethane resin having hydrophilic polar groups (mercapto groups) shows excellent dispersibility of magnetic powder when used as a binder for magnetic recording media. Magnetic recording media prepared by using the binder are excellent in surface-smoothness and durability. The mercapto groups contained in the magnetic layer react with isocyanate groups in the polyisocyanate to form thiourethane bonds to leave no hydrophilic polar groups, i.e., mercapto groups, and thus is excellent in moisture- and heat-resistance as well.The resin and the binding agent are advantageously used in the production of magnetic recording media, for example, magnetic tape, magnetic disc, etc.

    摘要: A first chopper between a laser device and a semiconductor substrate chops an excitation light at a specific frequency, and a second chopper between the first chopper and the semiconductor substrate chops the excitation light at a variable frequency higher than the first chopper. A photoluminescence light emitted by the semiconductor substrate when the semiconductor substrate is intermittently irradiated with the excitation light is introduced into a monochromator. A controller obtains the decay time constant T of the photoluminescence light from variation of the average intensity of the photoluminescence light when gradually increasing the chopping frequency of the excitation light by controlling the second chopper, and computes the life time &tgr; of the semiconductor substrate from an expression “&tgr;=T/C”, where C is a constant. An object of the invention is to accurately evaluate impurities, defects and the like in a semiconductor substrate by obtaining quantitatively the life time of the semiconductor substrate having a long life time.

    摘要: A wafer of the invention is a silicon wafer of 0.02 &OHgr;cm or less in resistivity for deposition of an epitaxial layer, and the number of crystal originated particles (COP) and the number of interstitial-type large dislocation loops (L/D) are respectively 0 to 10 per wafer. A wafer of the invention is an epitaxial wafer having an epitaxial layer being 0.1 &OHgr;cm or more in resistivity and 0.5 to 5 &mgr;m in thickness formed on this wafer by means of a CVD method. A wafer of the invention is OSF-free and hardly makes traces of COP and L/D appear on the surface of an epitaxial layer when the epitaxial layer is formed. By heat treatment in a semiconductor device manufacturing process after the epitaxial layer is formed, BMDs occur uniformly and highly in density in the wafer and a uniform IG effect can be obtained in the wafer.
