Abstract:
An integrated substrate processing system including a substrate carrier for supporting a plurality of substrates in stacked relation, the system comprising:a first chamber for thermally treating a single substrate held therein to a selected elevated temperature, wherein said first chamber includes a first substrate support;a second chamber for performing liquid etching on substrates positioned therein wherein said second chamber includes a second substrate support that is mounted for rotational motion about an axis substantially perpendicular to one surface of the substrate when the substrate is disposed on the second substrate support, and includes apparatus for selectively delivering liquid to one surface of the substrate disposed on the second substrate support for rotation therewith; anda substrate transport disposed for moving a selected one of the substrates between the carrier and the first chamber and the second chamber in a selected sequence for said substrate for elevating the temperature of the substrate in the first chamber substantially to a selected temperature, and for liquid etching the substrate in the second chamber.
