Claim Text:
1. A room-temperature bonding apparatus comprising: a plurality of first beam sources configured to emit a plurality of first activation beams which are irradiated to a first activation surface of a first substrate, respectively; a plurality of second beam sources configured to emit a plurality of second activation beams which are irradiated to a second activation surface of a second substrate, respectively; and a pressure welding mechanism configured to bond the first substrate and the second substrate by bringing the first activation surface and the second activation surface into contact after the first activation surface and the second activation surface are irradiated; a plurality of installation adjusting mechanisms corresponding to said plurality of first beam sources and said plurality of second beam sources, wherein one installation adjusting mechanism, corresponding to an optional beam source, of said plurality of installation adjusting mechanisms fixes the optional beam source on an optional installation position of a plurality of installation positions; a first support apparatus configured to support the first substrate when the first activation surface is irradiated by the plurality of first activation beams; and a second support apparatus configured to support the second substrate when the second activation surface is irradiated by the plurality of second activation beams, wherein the plurality of first beam sources are arranged to be rotationally symmetric with respect to a first rotation axis, wherein the first rotation axis is orthogonal to the first activation surface when the first activation surface is irradiated by the plurality of first activation beams, wherein said plurality of second beam sources are arranged to be rotationally symmetric with respect to a second rotation axis, and wherein the second rotation axis is orthogonal to the second activation surface when the second activation surface is irradiated with the plurality of second activation beams.
