  • Patent number: 10388492
    Abstract: A semiconductor processing member is provided, including a body and a plasma spray coating provided on the body. The coating is an ABO or ABCO complex oxide solid solution composition, where A, B and C are selected from the group consisting of La, Zr, Ce, Gd, Y, Yb and Si, and O is an oxide. The coating imparts both chlorine and fluorine plasma erosion resistance, reduces particle generation during plasma etching, and prevents spalling of the coating during wet cleaning of the semiconductor processing member.
    Type: Grant
    Filed: August 26, 2016
    Date of Patent: August 20, 2019
    Assignee: FM Industries, Inc.

  • Patent number: 7667944
    Abstract: The present invention discloses an electrostatic chuck for clamping work substrates, said chuck comprising three layers, where the dielectric constant of included non-conductive layers is selected to provide overall lower capacitance to the chuck. In the chuck assembly of the present invention, the top dielectric layer that is in contact with a substrate, such as, a wafer, has a dielectric constant that is preferably greater than about 5, with a resistivity that is preferably greater than about 1E6 ohm.m, whereas the bottom dielectric layer has a dielectric constant that is preferably less than about 5 and a resistivity that is preferably greater than about 1E10 ohm.m. The intermediate layer preferably has a conductive layer where the resistivity is less than about 1 ohm.m.

  • Patent number: 6754062
    Abstract: The invention is a hybrid chuck for securing workpieces with an electrostatic charge. The hybrid chuck includes a dielectric base for supporting the hybrid chuck. The dielectric base has a top surface and a conductive layer covers at least a portion of the top surface of the dielectric base. The conductive layer is conductive for receiving a current that creates an electrostatic charge and is non-metallic for maintaining the electrostatic charge without significant eddy current losses in the presence of dynamic electromagnetic fields. The top working surface covers the conductive layer and is flat for holding workpieces upon the receiving of the current to create the electrostatic charge in the conductive layer.
