Abstract:
Methods and apparatuses for filling features with metal materials such as tungsten-containing materials in a substantially void-free manner are provided. In certain embodiments, the method involves depositing an initial layer of a metal such as a tungsten-containing material followed by removing a portion of the initial layer to form a remaining layer, which is differentially passivated along the depth of the high-aspect ratio feature. The portion may be removed by exposing the tungsten-containing material to a plasma generated from a fluorine-containing nitrogen-containing gas and pulsing and/or ramping the plasma during the exposure.

Claim (Index 18):
The method of  claim 17 , wherein the plasma is pulsed between an ON state and an OFF state, wherein the plasma power during the OFF state is OW and the plasma power during the ON state is between about 50 W and about 3000 W.
