    摘要: A method of forming an integrated circuit structure includes providing a substrate; forming a metal feature over the substrate; forming a dielectric layer over the metal feature; and forming an opening in the dielectric layer. At least a portion of the metal feature is exposed through the opening. An oxide layer is accordingly formed on an exposed portion of the metal feature. The method further includes, in a production tool having a vacuum environment, performing an oxide-removal process to remove the oxide layer. Between the step of forming the opening and the oxide-removal process, no additional oxide-removal process is performed to the metal feature outside the production tool. The method further includes, in the production tool, forming a diffusion barrier layer in the opening, and forming a seed layer on the diffusion barrier layer.

    摘要: Electrochemical plating (ECP) apparatuses with auxiliary cathodes to create uniform electric flux density. An ECP apparatus for electrochemical deposition includes an electrochemical cell with an electrolyte bath for electrochemically depositing a metal on a substrate. A main cathode and an anode are disposed in the electrolyte bath to provide a main electrical field. A substrate holder assembly holds a semiconductor wafer connecting the cathode. An auxiliary cathode is disposed outside the electrochemical cell to provide an auxiliary electrical field such that a flux line density at the center region of the substrate holder assembly substantially equals that at the circumference of the substrate holder assembly.

    摘要: A method of forming a copper interconnect in an opening within a pattern is described. The copper interconnect has an Rs that is nearly independent of opening width and pattern density. A first copper layer having a concave upper surface and thickness t1 is formed in a via or trench in a dielectric layer by depositing copper and performing a first CMP step. A second copper layer with a thickness t2 where t2≦t1 and having a convex lower surface is deposited on the first copper layer by a selective electroplating method. The first and second copper layers are annealed and then a second CMP step planarizes the second copper layer to become coplanar with the dielectric layer. The invention is also a copper interconnect comprised of the aforementioned copper layers where the first copper layer has a grain density (GD1)≧GD2 for the second copper layer.
