Abstract
An apparatus for holding a substrate on a support layer in a processing chamber. The apparatus is directed to a susceptor system for a processing chamber in which a substrate is electrostatically held essentially flat. The apparatus includes a substrate support and a support layer composed of a dielectric material disposed on the substrate support. At least one lift pin is used for supporting the substrate relative to the support layer. A device is provided for moving each lift pin relative to the support layer. A device is also provided for producing a plasma within the processing chamber.
