发明名称 COPPER INTERCONNECT STRUCTURE AND METHOD FOR FORMING THE SAME
摘要 A copper interconnect structure in a semiconductor device comprises a dielectric layer having sidewalls and a surface defining an opening in the dielectric layer. The copper interconnect structure also comprises a barrier layer deposited on the sidewalls and the surface of the dielectric layer defining the opening. The copper interconnect structure further comprises a barrier/seed mixed layer deposited on the barrier layer. The copper interconnect structure additionally comprises an adhesive layer deposited on the barrier/seed mixed layer. The copper interconnect structure also comprises a seed layer deposited on the adhesive layer.
