Abstract:
1. A method for removing residue materials containing a polymer in a post metal etch process, comprising the steps of: introducing a substrate having a patterned etched metal layer into a plasma chamber; generating plasma from a gas comprising one or more fluorine compound containing etching gases at a temperature of from about 25 degrees C. to about 80 degrees C. and at a pressure of about 0.5 Torr to 10 Torr or less, for a time period of about 30 seconds, wherein at least a first portion of the residue is converted to volatile species and removed via pumping, wherein at least a second portion of the residue is converted to compounds that are soluble in CO exposing the substrate to a flow that contains CO
