Abstract:
1. A method for room-temperature bonding a plurality of substrates via intermediate members, comprising: providing said plurality of substrates, only a single physical sputtering source, and a plurality of targets such that said plurality of substrates is arranged at a position away from an axis line of said only a single physical sputtering source and at least one of said plurality of targets is arranged at a position away from said axis line, said axis line starting at a center of said only a single physical sputtering source and being parallel to a direction in which said only a single physical sputtering source faces, said axis line extending beyond said only a single physical sputtering source past said plurality of substrates and at least one of said plurality of targets; forming said intermediate members on surfaces to be bonded of said plurality of substrates by physically sputtering said plurality of targets including the at least one said target arranged at a position away from said axis line using said only a single physical sputtering source; activating said surfaces to be bonded of said plurality of substrates by physical sputtering using said only a single physical sputtering source; and bonding said plurality of substrates.
