Abstract:
Articles are transported from one position to another by being disposed in trays, which are carried within a portable magazine. The trays are automatically unloaded in sequence from the magazine and transported to a position in which the articles in the tray may be removed therefrom. The unloaded tray is then returned to the magazine and the next of the trays is removed from the magazine. The apparatus includes coding means on the magazine to indicate the status of the articles within each of the trays in the magazine.
Abstract:
A package for interconnecting a plurality of integrated circuit chips including a dielectric body having a plurality of intersecting planes and a plurality of metallized interconnection patterns located thereon. Conductive interconnecting lines connected to at least some of said metallized patterns located on different intersecting planes provide inter-plane electrical continuity, and input/output connectors connect to at least one of the metallized patterns for connecting to the outside world.
Abstract:
The invention is directed to a continuous vacuum multiprocessing system for treating, evaporation, or sputter vacuum depositing on a substrate or wafer for the preparation of semiconductors. The utilized structure comprises an annular chamber partitioned into alternating process and isolation compartments which are circularly arranged around a common (central) vacuum manifold. A circular transport ring, confined to the evacuated annular mechanically transports (via rotation) the substrates through the various serially connected compartments.
Abstract:
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.
Abstract:
A TARGET OF A DIELECTRIC MATERIAL IS MOUNTED IN SPACED RELATION TO A CATHODE, WHICH IS ISOLATED FROM THE SPUTTERING CHAMBER AND THE ANODE IN THE SPUTTERING CHAMBER BY THE TARGET AND ITS MOUNTING STRUCTURE. RF ENERGY IS TRANSFERRED FROM THE CATHODE TO THE TARGET, WHICH HAS AT LEAST A PORTION PARALLEL TO THE ANODE, THROUGH THE SPACE BY A DIELECTRIC COOLANT, A LIQUID METAL, OR A METALLIC PASTE. WHEN EITHER THE METALLIC PASTE OR THE LIQUID METAL IS EMPLOYED, THE CATHODE IS COOLED BY CIRCULTING A COOLANT SUCH AS WATER THERETHROUGH.
