摘要:
A interconnect structure is provided having a conductor with enhanced thickness. The conductor includes an upper portion and a lower portion, wherein the lower portion geometry is sufficient to increase the current-carrying capacity beyond that provided by the upper portion. The lower portion is formed by filling a trench within an upper dielectric region, and the upper portion is formed by selectively removing a conductive material from the upper dielectric surface except for regions directly above the lower portion. The upper and lower portions thereby form a conductor of enhanced cross-section which can be produced by modifying a via-etch mask, rather than having to reconfigure and/or move interconnect features formed by a metal mask.
