METAL-ON-METAL DEPOSITION METHODS FOR FILLING A GAP FEATURE ON A SUBSTRATE SURFACE

Molybdenum (Mo) metal-on-metal (MoM) deposition methods for providing true bottom-up fill in vias and/or other gap features in device structures. These device structures contain metal at the bottom surface and have dielectric sidewalls. The deposition process provides molybdenum growth only, in some cases, on the metal film/layer to provide a selective process that can be called a metal-on-metal (MoM) process. The Mo MoM deposition process described herein are not limited to thin films (e.g., films less than 50 Å) and can be used to deposit thicker films (e.g., greater than 50 Å in some cases and greater than 200 Å in other useful cases) on metal surfaces while no, or substantially no, deposition is found on dielectric surfaces.
