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 1):
A method of substrate processing comprising:\n providing a substrate with a first substrate surface of a first material and a second substrate surface of a second material, the substrate having at least one feature with a sidewall and a bottom, the sidewall formed by the first substrate surface and the bottom formed by the second substrate surface; forming a tungsten film on the substrate, the tungsten film having a seam formed within the feature and an overburden formed on the first substrate surface outside the feature; planarizing the substrate to remove the overburden from the first substrate surface so that a top of the tungsten film is about coplanar with the first substrate surface outside the feature; oxidizing the tungsten film to form a tungsten oxide pillar which extends from the at least one feature without a seam; and reducing the tungsten oxide pillar to tungsten, the tungsten forming a substantially seamless tungsten gapfill within the at least one feature.
