Abstract:
Embodiments of the invention provide processes for vapor depositing tungsten-containing materials, such as metallic tungsten and tungsten nitride. In one embodiment, a method for forming a tungsten-containing material is provided which includes positioning a substrate within a processing chamber containing a lid plate, heating the lid plate to a temperature within a range from about 120° C. to about 180° C., exposing the substrate to a reducing gas during a pre-nucleation soak process, and depositing a first tungsten nucleation layer on the substrate during a first atomic layer deposition process within the processing chamber. The method further provides depositing a tungsten nitride layer on the first tungsten nucleation layer during a vapor deposition process, depositing a second tungsten nucleation layer on the tungsten nitride layer during a second atomic layer deposition process within the processing chamber, and exposing the substrate to another reducing gas during a post-nucleation soak process.

Abstract:
A new method and structure is provided for the creation of a copper dual damascene interconnect. A dual damascene structure is created in the layer of dielectric, optionally a metal barrier layer is deposited over exposed surfaces of the dual damascene structure. A copper seed layer is deposited, the dual damascene structure is filled with copper. An anneal is applied to the created copper interconnect after which excess copper is removed from the dielectric. Of critical importance to the invention, a thin layer of oxide is then deposited as a cap layer over the copper dual damascene interconnect, an etch stop layer is then deposited over the thin layer of oxide for continued upper-level metallization.
