Abstract:
A dual face shower head magnetron, comprising:a) a pair of face plates, each plate having a plurality of holes for transporting a gas therethrough, said face places being electrically insulted from each other and forming an interior space therebetween; b) a means for supporting said face plates in a position essentially parallel to each other to form the interior space, said supporting means being electrically insulated from said face plates; c) at least one magnet supported in the interior space, said at least one magnet being electrically insulted from said face plates and said means for supporting said face plates; d) means for introducing gas into the interior space and out through the plurality of holes in said face plates in a manner such that the flow rate of the gas through each hole is substantially the same; e) means for providing electrical power to at least one of said face plates; wherein the interior space is essentially gas tight except for the plurality of holes and said means for introducing gas.
