  • Patent number: 5711848
    Abstract: A method for testing a semiconductor wafer processing step. An overlying electrical structure is created on a bare wafer to form a test wafer which simulates the surface contours of production wafers that will be exposed to the tested processing step. The overlying electrical structure of the test wafer is created using the same processing steps are used in manufacturing the overlying electrical structures of production wafers. Although the test wafers have the same surface contour as the production wafers they simulate, the test wafers are less expensive to manufacture because the test wafers do not include any underlying layers found in the production wafers which are not exposed during the tested processing step, and therefore the steps which form these layers can be omitted when making test wafers.

  • Patent number: 5665640
    Abstract: A method and apparatus for depositing a film on a substrate by plasma-enhanced chemical vapor deposition at temperatures substantially lower than conventional thermal CVD temperatures comprises placing a substrate within a reaction chamber and exciting a first gas upstream of the substrate to generate activated radicals of the first gas. The substrate is rotated within the deposition chamber to create a pumping action which draws the gas mixture of first gas radicals to the substrate surface. A second gas is supplied proximate the substrate to mix with the activated radicals of the first gas and the mixture produces a surface reaction at the substrate to deposit a film. The pumping action draws the gas mixture down to the substrate surface in a laminar flow to reduce recirculation and radical recombination such that a sufficient amount of radicals are available at the substrate surface to take part in the surface reaction.

  • Patent number: 5651808
    Abstract: A new carbothermic reaction process is described for the thermochemical processing of nanophase WC-Co powders. The process permits shorter reaction times, reduced temperatures, and finer microstructures compared to conventional processing methods.The process builds on our experience with spray conversion processing [1], but involves 1) chemical vapor infiltration reaction of the carbon infiltrant and particle substrate to from WC-CO; and 2) removal of any excess (unreacted) carbon by controlled gasification. A feature of the carbothermic reaction process is its adaptability to conventional WC-Co processing technology, as well as to spray conversion processing technology.The resulting power particles consist of a network of fine grains, (less than 100 nm) of WC and Co with interconnected fine porosity. Powder particles suitable for subsequent handling and consolidation are readily produced with diameters greater than 10 microns.

  • Patent number: 5629001
    Abstract: An orally administrable therapeutic protein is provided by combining the therapeutic protein with a stabilizing agent in an aqueous solution. The solution is coated onto nonpareils and microencapsulated with a water emulsifiable enteric coating composition. The microcapsules are orally administered. The coating protects the protein as it passes through the stomach. Upon reaching the small intestines, the basic pH of the intestinal juices will dissolve the coating, allowing the protein to be released and induce antigen specific immune response which has the specificity of the native molecule. The stabilizing agent protects the therapeutic protein from denaturation during the encapsulation process.

  • Patent number: 5627103
    Abstract: An interconnect between a conductor and a transistor body above a gate electrode is established by forming a conductor separated and alongside a gate electrode. Both the conductor and the gate electrode are coated with a dielectric material such as silicon dioxide. The silicon dioxide layer is subsequently coated with a thin layer of polysilicon and a contact hole is photolithographically etched through the polysilicon layer and through the silicon dioxide layer to establish a contact hole to said conductor. The polysilicon layer protects the silicon dioxide layer from impurities in the photolithography process. After the photolithographic mask is removed, a second layer of polysilicon is deposited on the first layer of polysilicon, coating the polysilicon layer and partially filling the contact hole, establishing a contact between the combined polysilicon layers and the conductor.
