Abstract: A heated substrate support and method for making the same is generally provided. In one embodiment, a heated support includes a first and second plates having a heating element disposed therebetween. The heating element is biased against the first plate to provide good heat transfer therewith. In another embodiment, a heated support includes a first metallic plate coupled to a second metallic plate and sandwiching at least one guide therebetween. A resistive heating element is laterally retained by the guide relative to the first plate. In another aspect of the invention, a heating chamber for heating a substrate is provided. In one embodiment, the heating chamber includes walls defining an interior volume and a plurality of heated support plates coupled to the walls. The support plates are generally stacked parallel to each other within the interior volume. A heating element is urged against each first support plate.

Abstract: In a first embodiment, a susceptor is provided having a substrate supporting surface and an internal support frame that provides mechanical strength in a plane orthogonal to the substrate supporting surface, and provides flexibility in a plane parallel to the substrate supporting surface.

Abstract: An apparatus through which a substrate may be transferred between a first chamber and a second chamber in which the first chamber is maintained at a high temperature relative to the ambient temperature of the second chamber. The apparatus comprises a passageway for receiving the substrate and a thermally isolating interface. The thermally isolating interface reduces heat transfer from the first chamber to the second chamber and allows for transfer of the substrate between the apparatus and the second chamber. The thermally isolating interface includes a hole having dimensions such that the substrate is transferrable through the thermally isolating interface.

Abstract: The present invention generally provides a system and method for supporting a substrate having a support frame that minimizes deflection encountered during thermal expansion in a processing chamber. In one embodiment, the support frame comprises one or more longitudinal members coupled to one or more transverse members. The transverse members preferably define a supporting surface on which a heated susceptor is mounted. The longitudinal member is preferably disposed below the heated susceptor, thus minimizing thermal expansion of the longitudinal member. Spacers made of thermally conductive material may be disposed at appropriate locations along the members to provide more uniform distribution of heat within the members.

Abstract: A substrate processing system includes a processing chamber and a plasma source located external to the chamber. A conduit connects the plasma source to an interior region of the chamber to provide a reactive species to the chamber interior for cleaning interior surfaces of the chamber. A shower head, disposed between the plasma source and an interior region of the chamber, can serve as an electrode and also can serve as a gas distribution mechanism. The shower head includes a surface treatment, such as a non-anodized aluminum outer layer, an electro-polished surface of bare aluminum, or a fluorine-based protective outer layer. The surface-treated shower head improves the rate of removal of materials deposited on the interior surfaces of the chamber during cleaning, reduces contamination of substrates during processing, and provides more efficient use of the power source used for heating the substrate during processing.

Abstract: A technique for heating a substrate support, such as a susceptor, includes establishing respective final temperature setpoints for first and second heating elements in the susceptor. The temperatures of the heating elements are raised to their respective final temperature setpoints based on a predetermined heating rate. The temperatures of the first and second heating elements are controlled so that the difference between the temperatures of the first and second heating elements does not exceed the predetermined value while the temperatures of the heating elements are raised to their respective final temperature setpoints. Controlling the temperatures includes setting interim setpoints for the first and second heating elements, where the interim setpoint for the heating element having the greater heating capacity depends on the current value of the interim setpoint of the other heating element and the predetermined value.

Abstract: A substrate handling apparatus includes a transfer arm having a substrate support. The apparatus includes at least one image acquisition sensor configured to acquire images of a substrate supported by the substrate support. In addition, the apparatus includes a controller coupled to the image acquisition sensor and configured to control the image acquisition sensor to acquire at least one image of the substrate supported on the substrate support. The controller is further configured to receive the images acquired by the image acquisition sensor and to determine an initial position of the substrate based on the acquired images. The controller is further coupled to the substrate support to control movement thereof to move the substrate to a new position based on the substrate's initial position. The apparatus also can be used to determine a substrate identification and to detect certain substrate defects either before or after processing the substrate in a thermal processing chamber.
