Patent ID: 6972490

Claim:
A bonding structure with compliant bumps, comprising: a device comprising: a first substrate acting as a carrier; at least a metal bonding pad on said first substrate, said metal bonding pad providing electrical conduction to said first substrate; a first protection layer on a surface of said first substrate, said first protection layer covering an outside of said metal bonding pad and providing insulation and protection; at least a compliant bump providing a conductive channel for said device; and at least a stopper for preventing said compliant bump from cracking during bonding; a second substrate having at least a conductive electrode; and a film between said device and said second substrate for bonding said device to said second substrate; wherein said compliant bump further comprises: a metal layer on top of said metal bonding pad and said first protection layer; at least a polymer bump on said metal layer; and a conductive layer covering said polymer bump and forming a conductive channel with said metal bonding pad and said metal layer.
