    摘要: Embodiments described herein generally related to a substrate processing apparatus, and more specifically to an improved showerhead assembly for a substrate processing apparatus. The showerhead assembly includes a chill plate, a gas plate, and a gas distribution plate having a top surface and a bottom surface. A plurality of protruded features contacts the top surface of the gas distribution plate. A fastener and an energy storage structure is provided on the protruded features. The energy storage structure is compressed by the fastener and axially loads at least one of the protruded features to compress the chill plate, the gas plate and the gas distribution plate.

    摘要: 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.

    摘要: 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 a substrate support assembly having primary heaters and spatially tunable heaters. A deviation profile is determined from a result of processing the first substrate. The spatially tunable heaters are controlled in response to the deviation profile to enable discrete lateral and azimuthal tuning of local hot or cold spots on the substrate support assembly in forming a second temperature profile. A second substrate is then processed using the second temperature profile.
