  • Publication number: 20080283502
    Abstract: A method and system is provided for improved polishing or planarizing of aluminum oxide and/or aluminum oxynitride substrates. Specifically, the composition comprises an abrasive, a liquid carrier, and a phosphorus-type mono-acid.

  • Publication number: 20060196849
    Abstract: An improved composition and method for polishing a sapphire surface is disclosed. The method comprises abrading a sapphire surface, such as a C-plane or R-plane surface of a sapphire wafer, with a polishing slurry comprising an abrasive amount of an inorganic abrasive material such as colloidal silica suspended in an aqueous medium having a salt compound dissolved therein. The aqueous medium has a basic pH and includes the salt compound in an amount sufficient to enhance the sapphire removal rate relative to the rate achievable under the same polishing conditions using a the same inorganic abrasive in the absence of the salt compound.

  • Patent number: 6942546
    Abstract: A sensing apparatus for detecting a processing endpoint of a multi-layer semiconductor wafer includes a light source to emit light against a surface of the semiconductor wafer, a color sensor to sense a reflection color from the surface of the semiconductor wafer in response to the incident light and to generate a sensor signal, and a decision circuit coupled to the color sensor and configured to decide whether the wafer processing endpoint has been reached based at least in part on the sensor signal. In another embodiment, a sensing apparatus is coupled to a movable structure to position the sensing apparatus to sense the surface of the semiconductor wafer.

  • Patent number: 5656554
    Abstract: A method for removing conductive metals on a semiconductor chip while leaving a foundation on which the conductive metal is in contact with substantially intact. The foundation includes a dielectric layer and a connecting stud. The dielectric layer is formed from a material which has a relatively high reactivity to an attack by a base, but has a relatively low reactivity to an attack by acid. A first planarization process is applied to the semiconductor chip, the first planarization process attacks the conductive metal at a high rate and is discontinued prior to when the connecting stud via is exposed to direct effects of the first planarization process. A second planarization process is applied to the semiconductor chip. The second planarization process attacks the conductive metal at a relatively high rate, but attacks the connecting stud at a low rate. The second planarization process substantially removes what is left of the conductive metal after the first planarization process.

  • Patent number: 4915519
    Abstract: An improved apparatus and process are described in which a direct negative is formed using commercially available multi-stylus recording heads. A negative precursor comprised of a transparent support and an opaque thermoplastic ink layer carried thereon, is brought into contact with an ink receiving medium comprised of a resistive layer and a thin conductive ink receiving layer thereon. Electrical currents are provided by the recording styli of the multi-stylus recording head to the resistive layer to provide sufficient heat to soften regions of the opaque ink brought into contact with the conductive layer, by which regions of said opaque ink are transferred to the ink receiving conductive layer. In this manner, a pattern of opaque ink regions is removed from the surface of said transparent support, whereby a direct negative is formed having light opaque and light transparent regions.

  • Patent number: 4800397
    Abstract: An improved apparatus and process are described in which metal images are transferred to a softenable receiving layer using commercially available multi-stylus recording heads. The transfer medium is comprised of a resistive layer and a thin metal layer thereon. Electrical currents are provided by the recording styli of the multi-stylus recording head. Localized electrical currents in the resistive layer provide sufficient heat in the metal layer to soften regions of a metable receiving layer when it is brought into contact with said heated metal layer. Metal imaging for use in printed circuit board manufacture and in formation of printing masters can be transferred by this technique.
