Abstract:
A method of fabricating a bonded-substrate that includes at least one active substrate and a base substrate upon which the active substrate is bonded by a selenidation reaction, comprising:forming a first multi-stacked layer by depositing alternating layers of a first material and a second material on a bonding surface of the active substrate, the first material including selenium, and the second material including a material selected from the group consisting of indium, gallium, antimony, and aluminum; forming a second multi-stacked layer by depositing alternating layers of the first material and the second material on a mounting surface of the base substrate; placing the first and second multi-stacked layers into contact with each other; and bonding the active and base substrates to each other by annealing the substrates in an inert ambient to form a compound bond layer that adhesively bonds the substrates to each other.
