摘要:
The present invention to provide a method of mounting a semiconductor laser component capable of preventing deterioration of laser characteristics and destruction of the semiconductor laser component due to residual stresses as well as preventing decrease of a lifetime due to increase in temperature of the semiconductor laser component. The method of mounting a semiconductor laser device which comprises a step of pressure bonding a semiconductor laser component on a submount by a collet while a bonding member is heated to be fused or melt on a submount by heating a table on which the submount is placed, for example, characterized in that the table and the collet are heated to a temperature higher than a fusing point of said bonding member so as not to occur the heat transfer substantially to a collet, and then heating of the table and the collet is terminated with maintaining the pressure bonding state.

A heatsink structure for solid-state image sensors includes a foil-like heatsink sheet made of a high heat conductivity material. The heatsink sheet has a first fixed portion fixed to a solid-state image sensor and a second fixed portion fixed to another member. The heatsink sheet also has a plurality of cutout portions formed along directions from the first fixed portion toward the second fixed portion. Thus, the heatsink structure can cool the solid-state image sensor while reducing any external-force loads applied to the solid-state image sensor with a relatively simple structure.
