    摘要: A plasma (56, 333) generating apparatus (10, 320, 450) wherein a stage (250, 300, 300A, 350, 400, 425) is constructed to keep the plasma on the substrate (S). A pair of electrically, non-conductive tubes (252, 252A, 303, 305, 303A, 305A 403, 405) are mounted on a conductive base plate (253,306,406) having holes (255, 306B) for gas flow and one of the tubes supports a conductive support plate (251, 301, 351, 401) for a substrate (S). An electrically conductive disk (304, 404) between the tubes is provided. An outer conductive tube (307, 418) is preferably used with larger diameter chambers. The stage is designed to prevent the plasma from falling below conductive support plate which preferably mounts a graphite insert (302, 352, 402) which supports the substrate.
