  • Thermal post-deposition treatment of halogen-doped films to improve film stability and reduce halogen migration to interconnect layers
    Patent number: 5763010
    Abstract: A method of stabilizing a halogen-doped silicon oxide film to reduce halogen atoms migrating from said film during subsequent processing steps. A halogen-doped film is deposited over a substrate and then subjected to a degassing step in which the film is briefly heated to a temperature of between about 300.degree. and 550.degree. C. before deposition of a diffusion barrier layer. It is believed that such a heat treatment step removes loosely bonded halogen atoms from the halogen-doped film and thus the treatment is referred to as a degassing step. In a preferred version of this embodiment, the halogen-doped silicon oxide film is an FSG film that is subjected to a degassing treatment for between about 35 and 50 seconds.

  • Process for evenly depositing ions using a tilting and rotating platform
    Patent number: 5763020
    Abstract: A process for depositing a layer of uniform thickness on an uneven surface of a substrate is disclosed. The layer could be deposited by plasma or chemical vapor deposition (CVD). The uneven surface of the substrate has horizontal surfaces and vertical sidewalls and is located on a movable platform. The platform is tilted and rotated as the layer is deposited so that the ions or the flow of chemical vapor reaches the horizontal surface and the sidewall at a similar incident angle. Thereby, the layer is evenly deposited and has a uniform thickness with proper coverage and planarization.

  • Stain inhibiting pigment composition
    Patent number: 5759705
    Abstract: A process of treating wood to reduce the tannin staining of coatings subsequently applied includes the steps of providing a solution of a zirconyl compound in a carrier liquid such as water, applying the solution to a wood surface, and, drying the solution. The pore structure of the wood is modified or sealed so that staining of coating compositions applied subsequently over the surface is reduced. The process is particularly beneficial in cases where the coating composition a clear or a light-colored latex paint, especially white. The preferred zirconyl compound is zirconyl acetate. The treating solution may be modified by addition thereto of a lanthanide compound, especially cerium, to provide UV light protection to a substrate and further by one or more metal cations to impart mildewicidal activity to the composition.

  • Scouring pad and process for making same
    Patent number: 5756161
    Abstract: A process and apparatus for impregnating a molten or viscous cleaning composition into a traveling, three dimensional, lofty, dense nonwoven web is disclosed. The composition is applied by an applicator manifold and is retained in the voids within the web. The velocity of the web and the flow of the cleaning composition are adjusted depending on the viscosity of the composition and the web density. Additionally, the viscosity of the composition can be controlled by altering its temperature or by altering the line pressure. The process eliminates the use of a doctor blade, spray system and application roll to meter the amount of cleaning composition into the web, and is suitable for the application of a molten or very viscous chemical compositions into a lofty, dense nonwoven web.

  • Method for producing surface-treated paper and dry end of a paper machine
    Patent number: 5756156
    Abstract: A method for producing surface-treated paper, in particular of fine paper, and a dry end of a paper machine that makes use of the method. A paper web that has been dewatered by pressing is dried in the forward dryer section, in which drying energy is applied to the paper web over the entire length of the forward dryer section asymmetrically in the z-direction from the side of the bottom face of the web. This step is carried out by a number of successive groups with single-wire draw that are open downward. In this manner, shrinkage of the web both in the machine direction and in the cross direction is reduced or at least partially prevented, which shrinkage tends to take place when the dry solids content becomes higher. Paper broke is removed from underneath the drying groups that are open downward substantially by the force of gravity onto the broke conveyor placed underneath.

  • Rapid aging technique for aerogel thin films
    Patent number: 5753305
    Abstract: This invention pertains generally to aging methods suited to aerogel thin film fabrication, and particularly to techniques for improving gel strength and/or aerogel dielectric constant by a rapid aging technique, which avoid damage or premature drying of wet gel thin films during aging. A substrate having a wet gel thin film deposited thereon is contacted with a saturated water vapor atmosphere, preferably at an elevated pressure and a temperature greater than 100.degree. C. The method may comprise a vapor-phase exchange step to remove low boiling point pore liquids such as ethanol prior to or during aging. The method may also comprise a vapor-phase exchange step to replace water in the wet gel with another pore liquid such as acetone to stop the aging process and prepare the wet gel for drying. A vapor-phase aging catalyst (e.g. ammonia) may also be used to enhance the aging process.

  • Apparatus and method for mounting soldering balls onto surfaces of electronic components
    Patent number: 5750199
    Abstract: An absorber head picks up a plurality of soldering balls from a container, and is shifted horizontally toward a substrate. In the midway of this shift movement, the absorber head is stopped just above a flux storage and then lowered to soak the soldering ball in the flux stored in the flux storage, thereby applying each soldering ball with an adequate amount of flux. Thereafter, the absorber head is again shifted horizontally until it reaches the substrate. Then, the absorber head lowers the soldering ball applied with flux, so that each soldering ball is mounted on a corresponding electrode provided on the substrate. If any soldering balls are left in the flux storage due to failure of the pickup operation by the absorber head, such soldering balls are surely collected in a groove by wiping movement of a squeegee which is associated with the flux storage.

    Abstract: An organically modified sol-gel method of preparing substantially crack-free aluminosilicates films is provided. Chelated aluminum alkoxide and polydimethylsiloxane are mixed in a 1:1 ratio by weight in a solvent and refluxed at approximately the boiling temperature of the solvent to produce a sol-gel liquid including polymerized aluminosilicates. The sol-gel liquid is cooled to room temperature. Additional solvent is added to the sol-gel liquid to reduce its viscosity. A substrate is coated with the reduced viscosity sol-gel liquid. The coating of sol-gel liquid on the substrate is dried to produce an organically modified aluminosilicates sol-gel film. The sol-gel film is heated, to enhance polymerization of the sol-gel film and to evaporate residual solvent, and then cooled.
