Abstract: A method of etching a target material exposed on a substrate that also includes a reservation material exposed on the substrate includes exposing both the target material and the reservation material to an oxygen source to selectively form oxide on the reservation material relative to the target material, and etching the target material using an etchant gas. The oxide on the reservation material slows an effective etch rate of the reservation material relative to an effective etch rate of the target material. The reservation material may have a similar or different material composition than the target material. The target material may be exposed in a first subset of recesses with a first aspect ratio and while the reservation material may be exposed in a second set of the recesses with a second aspect ratio higher than the first aspect ratio.
