  • Publication number: 20200369741
    Abstract: This application relates to recombinant human interferon-like proteins. In one embodiment a recombinant protein created by gene shuffling technology is described having enhanced anti-viral and anti-proliferative activities in comparison to naturally occurring human interferon like alpha 2b (HuIFN-?2b).

  • Publication number: 20200357675
    Abstract: Methods and apparatus for dechucking a wafer from a surface of an electrostatic chuck (ESC). In some embodiments, a method comprises reducing a pressure of a gas applied to a backside of the wafer to approximately zero psi; reducing a downward pressure in a cylinder bore of a lifting actuator to approximately atmospheric pressure while a processing volume of the processing chamber is in a vacuum state to create a constant upward force on the wafer, the constant upward force less than a breaking force of the wafer; and sweeping a voltage applied to the ESC to dechuck the wafer; and monitoring a sensor on the lifting actuator that is interposed between a chucking position of the lifting actuator and a transfer position of the lifting actuator to detect when the wafer is dechucked.

  • Patent number: 10745807
    Abstract: Embodiments of the present disclosure relate to a showerhead assembly for use in a processing chamber. The showerhead assembly includes a porous insert disposed in a space defined between a gas distribution plate and a base plate to moderate the corrosive radicals resulting from plasma ignition to reduce particle issues and metal contamination in the chamber. The porous insert is a conductive material, such as metal, used to reduce the gap electrical field strength, or may be a dielectric material such as ceramic, polytetrafluoroethylene, polyamide-imide, or other materials with a low dielectric loss and high electrical field strength under conditions of high frequency and strong electric fields. As such, the electrical breakdown threshold is enhanced. The porous insert may reduce and/or eliminate showerhead backside plasma ignition and may include multiple concentric narrow rings that cover gas holes of the gas distribution plate.
