Abstract:
Methods for filling a substrate feature with a seamless tungsten fill are described. The methods include depositing a tungsten film, oxidizing the tungsten film to a tungsten oxide pillar, reducing the tungsten oxide film to a seamless tungsten gapfill and optionally depositing additional tungsten on the tungsten gapfill.

Claim (Index 14):
A method of substrate processing comprising:\n providing a substrate with at least one feature formed in a substrate surface, the feature extending a distance from the substrate surface and having a sidewall and a bottom, the sidewall of the feature and the substrate surface comprising a first material and the bottom comprising a second material different from the first material; forming a tungsten film on the substrate so that there is a void within the tungsten film within the at least one feature and a tungsten overburden formed on the substrate surface; planarizing the substrate to remove the tungsten overburden from the substrate surface so that a top of the tungsten film is substantially coplanar with the substrate surface; oxidizing the tungsten film to form a pillar of tungsten oxide extending from the at least one feature without a seam; and reducing the pillar of tungsten oxide to form a substantially seamless tungsten gapfill within the at least one feature.
