    Abstract: Intermetal dielectric (IMD) and interlevel dielectric (ILD) that have dielectric constants (K) ranging from 2.0 to 2.6 are prepared from plasma or photon assisted CVD (PACVD) or transport polymerization (TP). The low K dielectric (LKD) materials are prepared from PACVD or TP of some selected siloxanes and F-containing aromatic compounds. The thin films combine barrier and adhesion layer functions with low dielectric constant functions, thus eliminating the necessity for separate adhesion and barrier layers, and layers of low dielectric constant.

  • Patent number: 6511716
    Abstract: Ultraviolet rays are radiated over a lubricant film formed on the surface of a recording medium such as a hard disk. The recording medium is then subjected to exposure to a bases. The radiation of the ultraviolet rays allows the lubricant film to uniformly spread over the surface of the recording medium. The repellency can be enhanced over the surface of the recording medium. The friction can be reduced on the recording medium. Moreover, when the recording medium is exposed to the base, organic acid existing on the surface of the recording medium and/or in the lubricant film can be transformed into salt. The organic acid can be washed off or removed from the surface of the recording medium and/or out of the lubricant film in this manner. Less organic acid greatly contributes to prevention of generation of corrosion mounds on the recording medium over a longer period.

  • Patent number: 6451421
    Abstract: An anodized micro-pore aluminum tag bearing indicia thereon wherein the micro-pore anodized aluminum has its micro-pores filled with the cured reside of a composition, which contains silicone resin having pendant groups selected from one or more of methyl groups or phenyl groups. The composition in the micro-pores was cured to a degree effective for marking by blackening thereof with a, e.g., CO2, laser beam, in the form of indicia thereon. The surface of the tag preferably is substantially free of said composition. The method for treating the surface of the anodized micro-pore aluminum tag for forming indicia thereon commences by applying the composition to the surface. Excess of the composition from the surface is removed to leave composition resident in said micro-pores. The composition in the micro-pores then is at least partially cured. A laser then can create the indicia by blackening the composition in the micro-pores.

  • Patent number: 6451392
    Abstract: A novel chemical adsorbate compound capable of forming a monomolecular thin film is provided. The chemical adsorbate compound is transparent and stable in the visible light range, and has a photosensitive group which causes a photochemical reaction in the ultraviolet light range. Utilizing the chemical adsorbate compound, a liquid crystal alignment film is also provided. The liquid crystal alignment film has an excellent thermal stability and alignment control performance. Utilizing liquid crystal alignment film, a liquid crystal display device is further provided. The liquid crystal display device achieves wide viewing angles and clear display images at small driving voltages. These are achieved by, as one example, providing a chemical adsorbate compound including a chalcone derivative having a COO group at the 4′ position in the chalcone skeleton and an —SiX3 group, where X is a halogen, at the molecular end adjacent to the COO group.

  • Patent number: 6440501
    Abstract: An apparatus for curing silicone rubber is constructed so as to perform a heating process and a curing process in a very short time without degradation of characteristics in piezoelectric elements so as to improve productivity. A piezoelectric component having uncured silicone rubber coated on the external peripheral surface thereof is held in a jig having a property of reflecting far infrared rays. The uncured silicone rubber coated on the external peripheral surface of the piezoelectric component is irradiated with far infrared rays by a far infrared panel heater so as to cure the silicone rubber.

  • Publication number: 20020098364
    Abstract: A method for fabricating silicone elastomer stamps with hydrophilic surfaces is provided. The concept of polymer grafting is used to produce the stamps. The stamps thus produced have the great advantage that grafting of a thin hydrophilic polymer on a hydrophobic PDMS surface can render PDMS stamps permanently hydrophilic. With such stamps it becomes possible to print aqueous or highly polar inks reproducibly over days and weeks.

  • Patent number: 6423378
    Abstract: The invention concerns the use of cross-linkable silicone compositions for fast, economical and simple impregnation and/or varnishing of flat joints (e.g. cylinder head gaskets). More precisely it concerns the use of silicone compositions cross-linkable under UV radiation, by cationic process and in the presence of specific phoinitiators selected among onium borates or organometallic complexes, of which the borate counter-anions contain at least a boron bound to at least a substituted phenyl (Me, F). The silicone liquid precursor is a polydimethylsiloxane (PDMS) substituted by cross-linking functional groups, by cationic process (Gfp) under UV of the epoxy of vinyloxy type. These Gfp are present at the rate of 0.15 to 2.0 pr kg of PDMS. The invention also relates to the method for impregnating/varnishing flat joints (e.g. cylinder head gaskets) using the specific PDMS composition+photoinitiator of borate type as well as the treated joints and the composition themselves.

  • Patent number: 6406758
    Abstract: A method of applying a protective coating to a touch screen panel. A coating material which cures at an elevated temperature is applied to a touch screen panel on at least one surface thereof. The panel is then heated to a temperature which does not adversely affect the panel by irradiating the panel imparting energy to the coating material to more fully cure the coating material in a shorter time period without damaging the panel.
