Abstract:
At least one opening having a biconvex shape is formed into a dielectric material layer. A void-free metallization region (interconnect metallic region and/or metallic contact region) is provided to each of the openings. The void-free metallization region has the biconvex shape and exhibits a low wire resistance.

Claim (Index 1):
A method of forming a semiconductor structure, said method comprising:\n forming a dielectric material layer having at least one opening located in said dielectric material layer, said at least one opening having a biconvex shape; forming a diffusion barrier material in said at least one opening and on a topmost surface of said dielectric material layer; forming a reflow enhancement layer on said diffusion barrier liner; forming a layer of a metal or metal alloy on said reflow enhancement layer; performing a reflow anneal to completely fill a remaining volume of said at least one opening with said metal or metal alloy of said layer of metal or metal alloy; and removing said layer of metal or metal alloy, said reflow enhancement layer, and said diffusion barrier material located outside of said at least one opening, wherein a portion of said of metal or metal alloy, a portion of said reflow enhancement layer, and a portion of said diffusion barrier material remaining within said at least one opening.
