    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.

    摘要: New and improved microwave plasma assisted reactors, for example chemical vapor deposition (MPCVD) reactors, are disclosed. The disclosed microwave plasma assisted reactors operate at pressures ranging from about 10 Torr to about 760 Torr. The disclosed microwave plasma assisted reactors include a movable lower sliding short and/or a reduced diameter conductive stage in a coaxial cavity of a plasma chamber. For a particular application, the lower sliding short position and/or the conductive stage diameter can be variably selected such that, relative to conventional reactors, the reactors can be tuned to operate over larger substrate areas, operate at higher pressures, and discharge absorbed power densities with increased diamond synthesis rates (carats per hour) and increased deposition uniformity.

    摘要: An improved ion generating apparatus for producing a plasma disk using magnets 34 and 35 around a region 16 in a chamber 15 positioned in a microwave cavity is described. The apparatus is particularly operated at a microwave frequency such that electron cyclotron resonance is produced in the plasma to create an accelerating surface for the electrons around and inside of the plasma. The apparatus can be operated to treat an article 100 in the plasma or a holder 39, with a grid 51 to withdraw particles or with a magnets 47 around an opening 48 forming a nozzle which with electron cyclotron resonance produces a neutral beam of charged particles. The apparatus is particularly useful as a plasma source especially for oxidation, etching and deposition.

    摘要: A plasma apparatus which generates a radio frequency (UHF or microwave) disk plasma 16 and a hybrid plasma 45 derived from the disk plasma. The microwave plasma acts as a source of excited ion and free radical species and electrons for the second plasma which is hybrid in that it contains species from both microwave and dc (or rf depending on bias) excitation. The hybrid plasma can be used to treat an article 43 with different species than are present in the disk plasma and provides more control in this regard than a single plasma.
