摘要 | A method for bonding one body to another, such as a laser device to a submount, uses a metallic layer composed of a Group VB metal, such as niobium, sandwiched between a non-metallic layer and solder layer formed by an approximate Au-Sn eutectic layer. Advantageously the Group VB layer is formed at a submount temperature of less than approximately 201 DEG C., advantageously less than approximately 125 DEG C., and preferably less than approximately 101 DEG C.-advantageously to a thickness in the approximate range 0.05 mu m to 0.2 mu m, or even thinner if pinholes do not develop. The non-metallic layer is located on one of the bodies, and the other body has a metallic coating advantageously capped with an Au layer. |
其他摘要 | 将一个主体与另一个主体(例如激光器件)结合到基座的方法使用由诸如铌的VB族金属组成的金属层,夹在非金属层和由近似Au-Sn形成的焊料层之间。共晶层。有利地,VB族层的底座温度低于约201℃,有利地低于约125℃,优选低于约101℃,有利地厚度约为0.05μm。如果针孔不发展,则为0.2微米,甚至更薄。非金属层位于其中一个主体上,另一个主体具有金属涂层,有利地覆盖有Au层。 |
