Abstract:
A method of etching is described. The method includes providing a substrate having a first material containing organic material and a second material that is different from the first material, forming a first chemical mixture by plasma-excitation of a first process gas containing an inert gas, and exposing the first material on the substrate to the first chemical mixture. Thereafter, the method includes forming a second chemical mixture by plasma-excitation of a second process gas containing C and O, and optionally a noble element, and exposing the first material on the substrate to the second plasma-excited process gas to selectively etch the first material relative to the second material.

Claim (Index 20):
The method of  claim 1 , further comprising:\n repeating the steps of forming the first chemical mixture, exposing the first material to the first chemical mixture, forming the second chemical mixture, and exposing the first material to the second chemical mixture to incrementally remove additional portions of the first material.
