Abstract:
Embodiments of the disclosed subject matter provide a device including a carrier plate, and a die including a mating surface with a patterned thin film of metal or metal oxide surface bonded to the carrier plate using a solder preform with voids that overlay the patterned thin film on the die, where the oxide surface is disposed opposite a moat in a mating surface of the carrier plate, and where the voided regions remain free of solder when the solder is reflowed.
