Abstract:
A dual bond pad structure for a wafer with laser die attachment and methods of manufacture are disclosed. The method includes forming a bonding layer on a surface of a substrate. The method further includes forming solder bumps on the bonding layer. The method further includes patterning the bonding layer to form bonding pads some of which comprise the solder bumps thereon. The method further includes attaching a laser diode to selected bonding pads using solder connections formed on the laser diode. The method further includes attaching an interposer substrate to the solder bumps formed on the bonding pads.
