    摘要: A supported plasma sputtering apparatus is described having shaped electrical fields in the electron discharge region between the cathode and anode and the sputter region between the target and substrate while such regions are free of any externally applied magnetic field to provide a high deposition rate which is substantially uniform over a wide area. Plasma shaping electrodes separate from the anode and target shape the electrical fields in the electron discharge region and the sputter region to provide a high density plasma. The anode surrounds the target to cause substantially uniform sputtering over a large target area. In one embodiment the anode is in the form of an annular ring surrounding a flat target surface, such anode being provided with a ribbed upper surface which shields portions of the anode from exposure to sputtered material to maintain the electron discharge for a long stable operation. Several other embodiments accomplish the same result by using different anodes which either shield the anode from sputtered material, remove the sputtered coating on the anode by heating, or simultaneously mix sputtered metal from the auxiliary target with sputtered insulator from the main target so the resultant coating is conductive. A radio frequency potential alone or together with a D.C. potential, may be applied to the target for a greater sputtering rate.

    摘要: A triode sputtering apparatus to deposit material on the surface of an article. The apparatus comprises an enclosure means for evacuating the enclosure, a means for establishing an ion plasma in the enclosure. An ion target, including two members with surfaces of the material to be sputtered, is located in the enclosure with the surfaces facing the ion plasma. The target members are electrically biased so that ions from the plasma will impinge on their surfaces and sputter material therefrom. An article having a surface to be coated is mounted in the enclosure so that the surface faces the ion plasma and the sputtering surfaces of the target which are at an acute angle to the surface of the article. An electron funnel is used to funnel electrons being supplied to the plasma between the article and the target and an elongated anode is used to attract electrons from the plasma. The apparatus may be used to coat 11 by 11 inch glass plates with a metallic layer having substantially uniform optical density.

    摘要: AN RF SPUTTERING APPARATUS HAS AN ELONGATED HOLLOW CYLINDRICAL TARGET SURROUNDING AN ELONGATED CYLINDRICAL CATHODE TO SHIELD THE CATHODE FROM A PARTIALLY EVACUATED CHAMBER IN WHICH THE TARGET IS DISPOSED. AN ELONGATED HOLLOW CYLINDRICAL ANODE IS DISPOSED IN SURROUNDING RELATION TO THE TARGET. THE TARGET IS SPACED FROM THE CATHODE SO THAT COOLING OF THE TARGET MAY OCCUR BY DIELECTRIC COOLANT FLOWING THEREBETWEEN WITH THE DIELECTRIC COOLANT ALSO TRANSFERRING RF POWER TO THE TARGET FROM THE CATHODE WHEN RF POWER IS APPLIED BETWEEN THE CATHODE AND THE ANODE. IN AN EXTENSION TO CONTINUOUS MODE DEPOSITION (AS OPPOSED TO BATCH MODE DEPOSITION), SUBSTRATES CAN HAVE VARYING THICKNESSES OF MATERIAL DEPOSITED THEREON FROM THE TARGET UNDER THE SAME SPUTTERING CONDITIONS BY MOVING EACH SUBSTRATE INTO THE CHAMBER FOR SUPPORT ON THE INNER SURFACE OF THE ANODE, ROTATING THE ANODE ABOUT THE TARGET AT A CONSTANT VELOCITY, AND THEN REMOVING EACH SUBSTRATE AFTER A PERIOD OF TIME. THE AMOUNT OF TIME THAT EACH OF THE SUBSTRATES IS SUPPORTED ON THE ANODE DETERMINES THE THICKNESS OF THE DEPOSITED MATERIAL ON THE SUBSTRATE.
