Abstract
Devices and techniques including process steps make use of recesses in conductive interconnect structures to form reliable low temperature metallic bonds. A fill layer is deposited into the recesses prior to bonding. First conductive interconnect structures are bonded at ambient temperatures to second conductive interconnect structures using direct bonding techniques, with the fill layers in the recesses in one or both of the first and second interconnect structures.
