Abstract:
1. A room-temperature bonding apparatus comprising: a vacuum chamber, an evacuation apparatus evacuating said vacuum chamber, a pair of substrate holders arranged to face each other in said vacuum chamber, a pressure bonding mechanism connected to at least one of said substrate holders to bond substrates to each other, each of the substrates is mounted on a corresponding one of the substrate holders, and only a single physical sputtering source, wherein a target irradiated with ion beams or atom beams emitted from said physical sputtering source is arranged in said vacuum chamber independently of said substrate holders, said pressure bonding mechanism and said physical sputtering source, wherein said target is mounted on a singular target substrate or a plurality of target substrates, and wherein said substrates arranged at a position away from an axis line of said physical sputtering source and said singular target substrate or at least one of said plurality of target substrates is arranged at another position away from said axis line, wherein said pair of substrate holders is arranged at a different position away from said axis line, said axis line starting at a center of said physical sputtering source and being parallel to a direction which said physical sputtering source faces, said axis line extending beyond said physical sputtering source past said substrates and said singular target substrate or at least one of said plurality of target substrates.
