Abstract:
The present disclosure describes methods which employ a patterning photolithography/etch operations to form self-aligned interconnects with multi-metal gap fill. For example, the method includes a first pattern structure and a second pattern structure formed over a dielectric layer. Each of the first and second pattern structures includes a pair of spacers, and a center portion between the pair of spacers. A first opening, self-aligned to a space between the first and second pattern structures, is formed in the dielectric layer. A first conductive material is deposited in the first opening. The center portion of the second pattern structure is removed to form a void above the dielectric layer and between the pair of spacers of the second pattern structure. A second opening, self-aligned to the void, is formed in the dielectric layer; and a second conductive material is deposited in the second opening.

Claim (Index 15):
A semiconductor device, comprising:\n a first interconnect layer formed over a substrate; a second interconnect layer disposed over the first interconnect layer and comprising conductive structures formed of first and second conductive materials, wherein the first and second conductive materials are different from one another.
