Layer structures for making direct metal-to-metal bonds at low temperatures in microelectronics

Layer structures for making direct metal-to-metal bonds at low temperatures and shorter annealing durations in microelectronics are provided. Example bonding interface structures enable direct metal-to-metal bonding of interconnects at low annealing temperatures of 150° C. or below, and at a lower energy budget. The example structures provide a precise metal recess distance for conductive pads and vias being bonded that can be achieved in high volume manufacturing. The example structures provide a vertical stack of conductive layers under the bonding interface, with geometries and thermal expansion features designed to vertically expand the stack at lower temperatures over the precise recess distance to make the direct metal-to-metal bonds. Further enhancements, such as surface nanotexture and copper crystal plane selection, can further actuate the direct metal-to-metal bonding at lowered annealing temperatures and shorter annealing durations.

METALLIZATION BARRIER STRUCTURES FOR BONDED INTEGRATED CIRCUIT INTERFACES

Composite integrated circuit (IC) device structures that include two components coupled through a hybrid bonded composite interconnect structure. The two components may be two different monolithic IC structures (e.g., chips) that are bonded over substantially planar dielectric and metallization interfaces. Composite interconnect metallization features formed at a bond interface may be doped with a metal or chalcogenide dopant. The dopant may migrate to a periphery of the composite interconnect structure and form a barrier material that will then limit outdiffusion of a metal, such as copper, into adjacent dielectric material.
