摘要： A substrate support system comprises a substrate holder having a plurality of passages extending between top and bottom surfaces thereof. The substrate holder supports a peripheral portion of the substrate backside so that a thin gap is formed between the substrate and the substrate holder. A hollow support member provides support to an underside of, and is configured to convey gas upward into one or more of the passages of, the substrate holder. The upwardly conveyed gas flows into the gap between the substrate and the substrate holder. Depending upon the embodiment, the gas then flows either outward and upward around the substrate edge (to inhibit backside deposition of reactant gases above the substrate) or downward through passages of the substrate holder, if any, that do not lead back into the hollow support member (to inhibit autodoping by sweeping out-diffused dopant atoms away from the substrate backside).

摘要： A substrate support system comprises a relatively thin circular substrate holder having a plurality of passages extending between top and bottom surfaces thereof. The substrate holder includes a single substrate support ledge or a plurality of substrate support spacer vanes configured to support a peripheral portion of the substrate backside so that a thin gap is formed between the substrate and the substrate holder. The vanes can be angled to resist backside deposition of reactant gases as the substrate holder is rotated. A hollow support member provides support to an underside of the substrate holder. The hollow support member is configured to convey gas (e.g., inert gas or cleaning gas) upward into one or more of the passages of the substrate holder. The upwardly conveyed gas flows into the gap between the substrate and the substrate holder. Depending upon the embodiment of the invention, the gas in the gap can then flow either (1) outward and upward around the substrate edge or (2) downward through passages of the substrate holder, if any, that do not lead back into the hollow support member. The gas that flows outward and upward around the substrate edge inhibits backside deposition of reactant gases above the substrate. The gas that flows downward through the passages that do not lead back to the support member advantageously inhibits autodoping by sweeping out-diffused dopant atoms away from the substrate front side. In one embodiment, the support member comprises a hollow multi-armed support spider that conveys gas into selected ones of the passages. In another embodiment, the support member comprises a bowl- or cup-shaped structure that conveys gas upward into all of the passages. In yet another embodiment, the support member comprises a bowl- or cup-shaped structure that conveys gas upward into all but one or more of the passages.

摘要： A wafer holder for supporting a wafer within a CVD processing chamber includes a vertically moveable lift ring configured to support the bottom peripheral surface of the wafer, and an inner plug having a top flat surface configured to support the wafer during wafer processing. The lift ring has a central aperture configured to closely surround the inner plug. When a wafer is to be loaded onto the wafer holder, the lift ring is elevated above the inner plug. The wafer is loaded onto the lift ring in the elevated position. Then, the lift ring is maintained in the elevated position for a time period sufficient to allow the wafer temperature to rise to a level that is sufficient to significantly reduce or even substantially prevent thermal shock to the wafer when the wafer is brought into contact with the inner plug. The lift ring is then lowered into surrounding engagement with the inner plug. This is the wafer processing position of the wafer holder.

摘要： 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.
