Reducing resistivity in interconnect structures of integrated circuits

Abstract:

An integrated circuit structure having improved resistivity and a method for forming the same are provided. The integrated circuit structure includes a dielectric layer, an opening in the dielectric layer, an oxide-based barrier layer directly on sidewalls of the opening, and conductive materials filling the remaining portion of the opening.

Abstract(Chinese):
