Claim:
1. A method of processing a substrate disposed within a substrate processing chamber, comprising: depositing a tungsten seed layer via a plasma enhanced chemical vapor deposition (PECVD) process atop the substrate and directly onto sidewalls and a bottom of a feature formed in a first surface of a dielectric layer of the substrate; exposing the substrate to a plasma formed from a first gas comprising a metal organic tungsten precursor to form a tungsten-containing barrier layer directly onto the tungsten seed layer, wherein a temperature of the processing chamber during plasma enhanced atomic layer deposition (PEALD) formation of the tungsten-containing barrier layer is about 175 to about 225 degrees Celsius; and depositing a tungsten fill layer directly onto the tungsten-containing barrier layer to fill the feature to the first surface via a plasma enhanced chemical vapor deposition process.
