Abstract:
Processing methods may be performed to form recesses in a semiconductor substrate. The methods may include oxidizing an exposed silicon nitride surface on a semiconductor substrate within a processing region of a semiconductor processing chamber. The methods may include forming an inert plasma within the processing region of the processing chamber. Effluents of the inert plasma may be utilized to modify the oxidized silicon nitride. A remote plasma may be formed from a fluorine-containing precursor to produce plasma effluents. The methods may include flowing the plasma effluents to the processing region of the semiconductor processing chamber. The methods may also include removing the modified oxidized silicon nitride from the semiconductor substrate.

Claim (Index 6):
The etching method of  claim 1 , wherein the remote plasma is formed in a region of the semiconductor processing chamber fluidly isolated from the processing region of the semiconductor processing chamber or is formed in a remote plasma unit fluidly coupled with the semiconductor processing chamber.
