  • Publication number: 20040170907
    Abstract: An attenuating embedded phase shift photomask blank that produces a phase shift of the transmitted light is formed with an optically translucent film made of metal, silicon, nitrogen and oxygen. An etch stop layer is added to improve the etch selectivity of the phase shifting layer. A wide range of optical transmission (0.001% up to 15% at 157 nm) is obtained by this process.

  • Publication number: 20040053026
    Abstract: An attenuating embedded phase shift photomask blank that produces a phase shift of the transmitted light is formed with an optically translucent film made of metal, silicon, nitrogen or metal, silicon, nitrogen and oxygen. A wide range of optical transmission (0.001% up to 20% at 193 nm) is obtained by this process. A post deposition process is implemented to obtain the desired properties (stability of optical properties with respect to laser irradiation and acid treatment) for use in industry. A special fabrication process for the sputter target is implemented to lower the defects of the film.

  • Patent number: 6656975
    Abstract: A silicone composition having a continuous phase of a polar organic liquid including particles of a silicone active material encapsulated within an organic encapsulating material which is a solid at 25° C. The silicone active material is sparingly soluble in the polar organic liquid at 25° C., but is substantially dissolved in the polar organic liquid at temperatures of from 40 to 100° C. The three phase contact angle between the organic encapsulating material, the silicone antifoam, and the polar organic liquid is below 130° C., with the angle measured through the silicone.

  • Publication number: 20030119917
    Abstract: The present invention relates to a dispersible silicone composition comprising a blend of (I) a silicone composition prepared by reacting (i) a polyorganosiloxane, (ii) a silicon compound, and (iii) a catalytic amount of a compound for promoting the reaction of the other components and (II) a polyisobutylene compound. The polyisobutylene oligomer or polyisobutylene polymer is effective as a dispersing agent for the silicone composition (I). The polyisobutylene-containing compositions are easier to handle, produce less waste, and their dispersion into mineral oil formulations is more efficient.

  • Patent number: 6000332
    Abstract: A method and materials for screen printing a substrate with raised designs. The raised designs allow for a lenticular effect through the printing of substantially parallel lines with varying heights in differing portions of the lines. The lenticular effects achieved include anticounterfeiting markings in bar codes and in the appearance of different colored images depending on the angle of view.

  • Patent number: 5977191
    Abstract: The present invention relates to a method for controlling foam in a foam producing system comprising adding to the foam producing system a dispersible silicone composition comprising (I) a silicone composition prepared by reacting (i) a polyorganosiloxane, (ii) a silicon compound, optionally (iii) a finely divided filler, and (iv) a catalytic amount of a compound for promoting the reaction of the other components and (II) a hydrocarbon oil. The hydrocarbon oil is effective as a dispersing agent for the silicone composition (I). The hydrocarbon oil-containing compositions are easier to handle, and produce less waste and its dispersion into mineral oil based formulations is more efficient.

  • Patent number: 5914362
    Abstract: A silicone-based antifoam composition, in the form of an emulsion, is prepared from the reaction of (A) a primary silicone composition and (B) a polydiorganosiloxane having condensable terminal groups in a nonpolar organic medium selected from the group consisting of polyisobutylene and mineral oil. The reaction of the primary silicone composition (A) and the polydiorganosiloxane (B) produces a secondary silicone composition, which forms the discontinuous phase of the emulsion and the nonpolar organic medium forms the continuous phase of the emulsion. The resulting composition of the invention exhibits antifoam efficacy greater than that of the primary silicone composition.

  • Patent number: 5801893
    Abstract: A method for adaptively detecting when portion of a magnetic tape is wrapped around a capstan of a magnetic tape cassette player includes the steps of transferring the magnetic tape from a supply reel to a take-up reel for a first rotation of the take-up reel, passing the magnetic tape across the capstan when the magnetic tape is being transferred, measuring a first set of pulses of a signal during the first rotation of the take-up reel, measuring a subsequent set of pulses during each subsequent set of a take-up reel, and stopping the rotation of the take-up reel when the subsequent set of pulses varies from the subsequent of pulses immediately proceeding to prevent the magnetic tape from wrapping around the capstan.
