Abstract: PURPOSE:To enhance the reliability by a method wherein a ternary alloy of Sn, Ag and Sb is used as a solder agent for an outermost surface in order to eliminate a defect of the bonding strength and to keep a solder surface state stable. CONSTITUTION:A submount which is inserted and fixed, as a thermal stress relaxation material, between a semiconductor laser element and a metal block tor heat dissipation use is constituted in such a way that a barrier layer 2 composed of a Ti layer 21, an Ni layer 22 and an Ag layer 23 is formed on both faces of a conductive Si substrate 1 by evaporation or the like and that a layer 3 of a ternary alloy solder composed of Sn, Ag and Sb is formed on the barrier layer 2. Since this solder layer 3 is soft at a hardness of 3.5 Hv, a thermal stress strain which is exerted on the laser element fixed onto the submount is small. Since the layer 3 is hardly subjected to a thermal fatigue due to a heat cycle characteristic, a chip is not detached due to a defect of the bonding strength. Wince a surface state of the layer 3 is hard to change, the quantity of light which is incident on a photodiode for monitoring a laser beam output is not changed with the passage of time; a fluctuation in a characteristic can be reduced.
