Classification: CPC H  B | IPC H

Claim 0:
1. A bonded structure comprising:
a first element comprising a first conductive interface feature and a first nonconductive interface feature; and
a second element comprising a second conductive interface feature and a second nonconductive interface feature, the second element being stacked on the first element along a vertical dimension, the second conductive interface feature bonded to the first conductive interface feature along a bonding interface and the second nonconductive interface feature bonded to the first nonconductive interface feature along the bonding interface,
wherein a first cross-section of the first conductive interface feature taken along a lateral dimension transverse to the vertical dimension of the first conductive interface feature has a first overall thickness along the vertical dimension,
wherein a second cross-section of the first conductive interface feature along the lateral dimension of the first conductive feature has a second overall thickness along the vertical dimension, the first overall thickness different from the second overall thickness, and
wherein the first conductive interface feature has a back side opposite the bonding interface, the nonconductive interface feature disposed over the back side of the first conductive interface feature.
