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 4):
The etching method of  claim 1 , wherein the fluorine-containing precursor comprises anhydrous hydrogen fluoride.
