  • Patent number: 9184072
    Abstract: An apparatus and method are described for processing workpieces in a treatment process. A multi-wafer chamber defines a chamber interior including at least two processing stations within the chamber interior such that the processing stations share the chamber interior. Each processing station includes a plasma source and a workpiece pedestal for exposing one of the workpieces to the treatment process using a respective plasma source. The chamber includes an arrangement of one or more electrically conductive surfaces that are asymmetrically disposed about the workpiece at each processing station in a way which produces a given level of uniformity of the treatment process on a major surface of each workpiece. A shield arrangement provides an enhanced uniformity of exposure of the workpiece to the respective one of the plasma sources that is greater than the given level of uniformity that would be provided in an absence of the shield arrangement.

  • Patent number: 7972444
    Abstract: A workpiece support is disclosed defining a workpiece-receiving surface. The workpiece support includes a plurality of fluid zones. A fluid, such as a gas, is fed to the fluid zones for contact with a workpiece on the workpiece support. The fluid can have selected thermoconductivity characteristics for controlling the temperature of the workpiece at particular locations. In accordance with the present disclosure, at least certain of the fluid zones are at different azimuthal positions. In this manner, the temperature of the workpiece can be adjusted not only in a radial direction but also in an angular direction.

  • Publication number: 20070051471
    Abstract: One embodiment of the present invention is a stripping reactor that includes: (a) a remote plasma source disposed to output a gas; (b) a gas distribution plate connected to ground that transmits the gas output from the remote plasma source to a processing chamber; (c) a wafer support disposed in the processing chamber; (d) a wafer support assembly disposed about the wafer pedestal that includes an outer conductive peripheral structure connected to ground; and (e) an RF power supply connected to supply RF power to the wafer support.

  • Publication number: 20070019278
    Abstract: A spatial light modulator (SLM) is disclosed that increases speed and efficiency of an SLM through the use of a perforated hinge. The hinge may take many forms, but generally includes an elongated body having holes therein along its longitudinal direction. One or more electrodes are charged with a predetermined voltage in order rotate a reflecting surface towards the electrodes through electrostatic attraction. The perforations within the hinge results in the hinge being made from less material so that it is less sensitive to hinge thickness variations that can occur during the manufacturing process. Consequently, the perforated hinge allows for more stable, uniform mirror rotation.

  • Publication number: 20060087717
    Abstract: Hydrogen cleave silicon process for light modulating mirror structure using single crystal silicon as the base cross-member. Existing processes use two critical alignment steps that can contribute to higher actuation voltages and result in lower manufacturing yields. The hydrogen cleave process simplifies the manufacturing process to one step: transferring a thin film of single crystal silicon to the CMOS substrate, resulting in minimal alignment error and providing large bonding area.
