Abstract: 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.

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.

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.

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 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.

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.

The process kit has a support ring comprising an upper surface having an inner edge disposed at a first height and an outward edge disposed at a second height less than the first height, the inner edge having a greater thickness than the outward edge. An edge ring is disposed on the support ring, an inner surface of the edge ring interfaced with the inner edge of the support ring. A cover ring is disposed outward of the edge ring, the edge ring independently moveable relative to the support ring and the cover ring. Push pins are disposed inward of the cover ring, the push pins operable to elevate the edge ring while constraining radial movement of the support ring.
