  • Publication number: 20180061616
    Abstract: Embodiments disclosed herein generally relate to a pumping system for a plasma processing apparatus. The pumping system includes a first pump path, a second pump path, a first valve, and a second valve. The first pump path couples an opening of a substrate support assembly of the processing chamber to an exhaust port of the processing chamber. The second pump path couples the opening of the substrate support assembly to an evacuation region of the processing chamber. The first valve is positioned in the first pump path. The first valve is configurable between a first state and a second state. The second valve is positioned in the second pump path. The second valve is configurable between the first state and the second state.

  • Publication number: 20180053666
    Abstract: A substrate carrier is described with an array of independently controllable heater elements. In one example an apparatus includes a substrate carrier to carry a substrate for processing, a plurality of resistive heating elements in the carrier to heat the substrate by heating the carrier, a power supply to supply power to the heating elements, a power controller to provide a control signal, the control signal to control an amount of current applied to each of the heating elements, and a plurality of power interfaces in the carrier each coupled to a heating element to receive the power from the power supply and the control signal from the controller and to modulate the power applied to a respective coupled heating element in response to the control signal.

  • Publication number: 20180040498
    Abstract: Precision screen printing is described that is capable of sub-micron uniformity of the metallization materials that are printed on green sheet ceramic. In some examples, puck is formed with electrical traces by screen printing a paste that contains metal on a ceramic green sheet in a pattern of electrical traces and processing the printed green sheet to form a puck of a workpiece carrier. In some example, the printing includes applying a squeegee of a screen printer to the printed green sheet in a squeegeeing direction while the green sheet is on a printer bed of the screen printer. The method further includes mapping the printer bed at multiple locations along the squeegeeing direction, identifying non-uniformities in the printer bed mapping, and modifying a printer controller of the screen printer to compensate for mapped non-uniformities in the printer bed.

  • Publication number: 20180019104
    Abstract: Embodiments disclosed herein relate to a substrate processing chamber component assembly with plasma resistant seal. In one embodiment, the semiconductor processing chamber component assembly includes a first semiconductor processing chamber component, a second semiconductor processing component, and a sealing member. The sealing member has a body formed substantially from polytetrafluoroethylene (PTFE). The sealing member provides a seal between the first and second semiconductor processing chamber components. The body includes a first surface, a second surface, a first sealing surface, and a second sealing surface. The first surface is configured for exposure to a plasma processing region. The second surface is opposite the first surface. The first sealing surface and the second sealing surface extend between the first surface and the second surface. The first sealing surface contacts the first semiconductor processing chamber component.

  • Publication number: 20170213758
    Abstract: Apparatuses including a height-adjustable edge ring, and methods for use thereof are described herein. In one example, a substrate support assembly includes a height-adjustable edge ring, and the substrate support assembly is located within a process chamber. The substrate support assembly includes an electrostatic chuck, an edge ring positioned on a portion of the electrostatic chuck, and one or more actuators to adjust the height of the edge ring via one or more push pins. The height-adjustable edge ring can be used to compensate for erosion of the edge ring over time. In addition, the height-adjustable edge ring can be removed from the process chamber via a slit valve opening without venting and opening the process chamber. The height-adjustable edge ring can be tilted by the one or more actuators in order to improve azimuthal uniformity at the edge of the substrate.

  • Publication number: 20160345384
    Abstract: Implementations described herein provide a method for processing a substrate on a substrate support assembly which enables both lateral and azimuthal tuning of the heat transfer between an electrostatic chuck and a substrate. The method includes processing a first substrate using a first temperature profile on the ESC having primary heaters and spatially tunable heaters. A deviation profile is determined from a result of processing the first substrate from a target result profile. The first temperature profile is adjusted to a second temperature profile on the ESC based on the deviation profile. Adjusting to the second temperature profile includes incrementing the power to one or more spatially tunable heaters in one or more discrete locations corresponding to the deviations profile. A second substrate is then processed on the ESC using the second temperature profile.
