Abstract
A method of manufacturing a semiconductor laser device includes the steps of: providing a laser chip, in which a semiconductor layer is formed on a substrate, a supporting plate which supports the laser chip, a mounting plate, a first solder film positioned between the laser chip and the mounting plate and a second solder film positioned between the mounting plate and the supporting plate to form a stacked laser chip structure; applying heat to the stacked laser chip structure sufficient to melt the first solder film and the second solder film; and, applying pressure to the stacked laser chip structure during the heating step to cause simultaneous adhering of the laser chip, the mounting plate and the supporting plate to each other.
