See full text

A structure includes a substrate, a metallization layer on the substrate, and a cap layer on the metallization layer, wherein the cap layer includes a cap platinum (Pt) layer on the metallization layer, and a cap gold (Au) layer deposited on the Pt cap layer. A method of bonding a laser diode submount assembly to a hard disk assembly slider includes disposing a first metallization layer on the slider, disposing a cap layer on the first metallization layer, wherein the cap layer includes a cap Pt layer on the first metallization layer, and a cap Au layer deposited on the cap Pt layer, disposing a second metallization layer on the laser diode submount assembly, and forming a solder bond between the cap layer on the slider and the second metallization layer on the laser diode submount assembly.
