    摘要: Anti-reflective coating materials for deep ultraviolet photolithography include one or more organic light-absorbing compounds incorporated into spin-on-glass materials. Suitable absorbing compounds are strongly absorbing over wavelength ranges around wavelengths such as 365 nm, 248 nm, and 193 nm that may be used in photolithography. A method of making absorbing spin-on-glass materials includes combining one or more organic absorbing compounds with alkoxysilane or halosilane reactants during synthesis of the spin-on-glass materials.

    摘要: A method for making a glass frit paste is provided. First, nitrocellulose is dissolved in a high vapor pressure solvent of the nitrocellulose to make a solution. A portion of the solution is then mixed with alpha-terpineol to form a vehicle. Glass frit is mixed with the vehicle and then ground to form the paste. During the grinding step most of the high vapor pressure solvent evaporates. The resulting paste has a composition comprising about 0.3-12.0 wt. % nitrocellulose, about 0.5-2.0 wt. % of a high vapor pressure solvent of said nitrocellulose, about 14.0-25.0 wt. % alpha-terpineol, and the remainder glass frit.

    摘要: A thermomechanical pressing ("TMP") method for obtaining rapidly a high density (1.2 g/cm.sup.3 or higher) carbon/carbon composite preform from any carbon fiber including PAN-based carbon fibers and industrial coal-tar or petroleum pitches (including synthetic derivatives) having a melting point m.p.=80-350.degree. C. Green preforms may be prepared from mixtures of carbon fibers and pitch, and the resulting mixture is formed to impart a cylindrical shape to the green preform. The green preform is charged into a metallic mold where it is heated, stabilized, pressurized for a period of time, and cooled.

    摘要: The invention provides a method for producing carbon/carbon composite honeycomb structures which have not only the mechanical properties associated with carbon/carbon materials but high thermal conductivities (>200 w/m-k) as well. A honeycomb structure comprising a low-modulus pitch precursor carbon fiber composite is heated or carbonized to drive off volitiles, densified at low pressure by CVD/CVI to provide a graphitizable carbon matrix, and then heat treated to graphitize both the carbon fiber and the carbon matrix. The resulting honeycomb structure has a high thermal conductivity with an increased fiber modulus and may be used, for example, for making heat transfer devices.
