Abstract
In an optical semiconductor device including a semiconductor laminated body including at least a light emitting layer, a first metal body including at least one first metal layer formed on the semiconductor laminated body, a support substrate, a second metal body including at least one second metal layer formed on the support substrate, and at least one adhesive layer formed in a surface side of at least one of the first and second metal bodies, the semiconductor laminated body is coupled to the support substrate by applying a pressure-welding bonding process upon the adhesive layer to form a eutectic alloy layer between the first and second metal bodies. At least one of the first and second metal layers has a triple structure formed by two tight portions and a coarse portion sandwiched by the tight portions.
