Abstract:
Embodiments of methods and apparatus for filling a feature disposed in a substrate are disclosed herein. In some embodiments, a method for filling a feature disposed in a substrate includes (a) depositing a metal within the feature to a first predetermined thickness in a first process chamber; (b) depositing the metal within the feature to a second predetermined thickness in a second process chamber; (c) etching the metal deposited in (b) to remove an overhang of the metal at a top of the feature in a third process chamber different than the first and second process chambers; and (d) subsequent to (c), filling the feature with the metal in a fourth process chamber different than the first and third process chambers.

Claim (Index 8):
The method of  claim 1 , wherein the third process chamber is an etch chamber, and wherein (c) comprises:\n (1) oxidizing an exposed layer of the metal deposited on the substrate using an oxidizing precursor; (2) purging the oxidizer precursor from the etch chamber; (3) flowing a reducing agent into the etch chamber to react with the oxidized layer and form an organometallic product and etch away the oxidized layer; and (4) purging the organometallic product from the etch chamber.
