    Abstract: A substrate holder for processing a semiconductor substrate that minimizes substrate non-uniformities as well as backside damage. The substrate holder includes one or more support elements, such as a plurality of veins configured in an annular ring to support an outer edge of a substrate. The veins are configured to support a substrate of a particular size in a support plane defined by the top surfaces of the veins. The substrate holder also has one or more annular grooves formed in the top surface of the holder. In a preferred embodiment, the substrate holder also has a raised annular ring positioned radially inward of the grooves and the support elements. The top surface of the raised annular ring is no higher that the top surfaces of the veins.

    Abstract: An apparatus and method to position a wafer (16) onto a wafer holder (200) and to maintain a uniform wafer temperature is disclosed. The wafer holder or susceptor (200) comprises a recess or pocket (202) whose surface (229) is concave and includes a grid containing a plurality of grid grooves (222) separating protrusions (220). The concavity and grid grooves define an enclosed flow volume (248) between a supported wafer (16) and the susceptor surface, as well as an escape area, or total cross-sectional area of the grid grooves (222) opening out from under the periphery of the wafer (16). These are chosen to reduce the wafer slide and curl during wafer drop-off and wafer stick during wafer pick-up, while improving thermal uniformity and reducing particle problems. In another embodiment, centering locators (250 or 252) in the form of thin, radially placed protrusions are provided around the edge of a susceptor pocket (202) to reduce further the possibility of contact between the wafer and the outer shoulder (206) of the susceptor. These features help to achieve temperature uniformity, and therefore quality of the process result, across the wafer during processing.

    Abstract: A substrate support system comprises a substrate holder for supporting a substrate. The substrate holder comprises an interior portion sized and shaped to extend beneath most or all of a substrate supported on the substrate holder. The substrate holder has mass density that varies, preferably in order to compensate for variations in substrate temperature owing to surface geometry variations of the interior portion, so as to provide a more uniform thermal coupling between the substrate and substrate holder. The substrate holder is preferably configured to be spaced further apart from a substrate at the center than at the outer perimeter.

    Abstract: Improvements in the design of a low mass wafer holder are disclosed. The improvements include the use of peripherally located, integral lips to space a wafer or other substrate above the base plate of the wafer holder. A uniform gap is thus provided between the wafer and the base plate, such as will temper rapid heat exchanges, allow gas to flow between the wafer and wafer holder during wafer pick-up, and keep the wafer holder thermally coupled with the wafer. At the same time, thermal disturbance from lip contact with the wafer is reduced. Gas flow during pick-up can be provided through radial channels in a wafer holder upper surface, or through backside gas passages. A thicker ring is provided at the wafer holder perimeter, and is provided in some embodiments as an independent piece to accommodate stresses accompanying thermal gradients. A self-centering mechanism is provided to keep the wafer holder centered relative to a spider which is subject to differential thermal expansion.
