    Abstract: In a first aspect, a substrate positioning system includes a plurality of pushers arranged in a spaced relation about a stage adapted to support a substrate. Each pusher is adapted to assume a retracted position so as to permit the substrate to be loaded onto and unloaded from the stage, extend toward an edge of the substrate that is supported by the stage, contact the edge of the substrate, and continue extending so as to cause the substrate to move relative to the stage until the substrate is calibrated to the stage. Numerous other aspects are provided.

  • Patent number: 7147827
    Abstract: A chemical control system for controlling the chemistry of a chemical solution having predetermined chemical constituents in a plating system, such as a NiFe plating system, employs a mix container for containing a plating solution and a hold container for containing a plating solution delivered from the mix container. A precision delivery arrangement delivers a precise predetermined quantum of a predetermined constituent of the plating solution to multiple mix containers and the hold containers. Transfer of plating solution between the mix and hold containers is effected by a transfer pump. Nitrogen gas that has been humidified with deionized water protects the plating solution from either acquiring water or becoming dehydrated, the humidified nitrogen gas being humidified to a predetermined relative humidity with respect to the temperature of the plating solution in the mix container. This is achieved by urging the nitrogen gas through a column that is at the same temperature as the plating solution.

  • Patent number: 7144606
    Abstract: The present invention generally provides improved adhesion and oxidation resistance of carbon-containing layers without the need for an additional deposited layer. In one aspect, the invention treats an exposed surface of carbon-containing material, such as silicon carbide, with an inert gas plasma, such as a helium (He), argon (Ar), or other inert gas plasma, or an oxygen-containing plasma such as a nitrous oxide (N2O) plasma. Other carbon-containing materials can include organic polymeric materials, amorphous carbon, amorphous fluorocarbon, carbon containing oxides, and other carbon-containing materials. The plasma treatment is preferably performed in situ following the deposition of the layer to be treated. Preferably, the processing chamber in which in situ deposition and plasma treatment occurs is configured to deliver the same or similar precursors for the carbon-containing layer(s). However, the layer(s) can be deposited with different precursors.

  • Publication number: 20060269693
    Abstract: High tensile stress in a deposited layer such as silicon nitride, may be achieved utilizing one or more techniques, employed alone or in combination. High tensile stress may be achieved by forming a silicon-containing layer on a surface by exposing the surface to a silicon-containing precursor gas in the absence of a plasma, forming silicon nitride by exposing said silicon-containing layer to a nitrogen-containing plasma, and then repeating these steps to increase a thickness of the silicon nitride created thereby. High tensile stress may also be achieved by exposing a surface to a silicon-containing precursor gas in a first nitrogen-containing plasma, treating the material with a second nitrogen-containing plasma, and then repeating these steps to increase a thickness of the silicon nitride formed thereby. In another embodiment, tensile film stress is enhanced by deposition with porogens that are liberated upon subsequent exposure to UV radiation or plasma treatment.

  • Patent number: 7141440
    Abstract: A property of a layer is measured by: (1) focusing a heating beam on a region (also called “heated region”) of a conductive layer (2) modulating the power of the heating beam at a predetermined frequency that is selected to be sufficiently low to ensure that at any time the temperature of an optically absorbing layer is approximately equal to (e.g., within 90% of) a temperature of the optically absorbing layer when heated by an unmodulated beam, and (3) measuring the power of another beam that is (a) reflected by the heated region, and (b) modulated in phase with modulation of the heating beam. The measurement in act (3) can be used directly as a measure of the resistance (per unit area) of a conductive pad formed by patterning the conductive layer. Change in measurement across regions indicates a corresponding change in resistance of the layer.
