Abstract:
Exemplary etching methods may include flowing a hydrogen-containing precursor into a substrate processing region of a semiconductor processing chamber. The methods may include flowing a fluorine-containing precursor into the substrate processing region. The methods may include contacting a substrate housed in the substrate processing region with the hydrogen-containing precursor and the fluorine-containing precursor. The substrate may define a trench. A spacer may be formed along a sidewall of the trench, and the spacer may include a plurality of layers including a first layer of a carbon-containing material, a second layer of an oxygen-containing material, and a third layer of a carbon-containing material. The second layer of the spacer may be disposed between the first layer and third layer of the spacer. The methods may also include removing the oxygen-containing material.

Claim (Index 13):
A removal method comprising:\n flowing water vapor into a substrate processing region at a temperature below or about 0\u00b0 C.; forming a solid layer of water on a substrate housed in the substrate processing region, wherein the substrate defines a trench, wherein a spacer is formed along a sidewall of the trench, wherein the spacer includes a plurality of lateral layers including a first layer of a carbon-containing material adjacent a sidewall of the trench, a second layer comprising an oxygen-containing material, and a third layer of a carbon-containing material, wherein the second layer of the spacer is disposed between the first layer of the spacer and third layer of the spacer, and wherein the solid layer of water is formed on an exposed surface of each layer of the spacer; flowing a fluorine-containing precursor into the substrate processing region of a semiconductor processing chamber; permeating the solid layer of water with the fluorine-containing precursor; and removing the second layer of the spacer.
