Abstract:
1. A deposition system, said deposition system comprising in combination: a) a vacuum reaction chamber; b) an immovable disc shaped holder having a perimeter and located within said chamber for supporting and heating a substrate of silicon, said holder including an imperforate substrate supporting surface defined by the perimeter of said holder; c) a heater for heating the substrate; d) apparatus located within said chamber, said apparatus being adapted to direct material from a target towards the substrate; e) an electrode movable within said chamber to a first position toward said holder for shielding the substrate and to a second position away from said holder to expose the substrate; f) a source for RF power; g) a RF transfer switch for applying RF power from said source of RF power; h) an impedance matching network interconnecting said RF transfer switch with a further electrode within said chamber; and i) a first source of vacuum for creating a first level of vacuum within said chamber and a second source of vacuum for creating a second level of vacuum within said chamber.
