Abstract
One method disclosed herein includes, among other things, forming a process layer on a substrate, forming a carbon-containing silicon dioxide layer above the process layer and forming a patterned mask layer above the carbon-containing silicon dioxide layer. The patterned mask layer exposes portions of the carbon-containing silicon dioxide layer. A material modification process is performed on the exposed portions of the carbon-containing silicon dioxide layer to generate modified portions, and the modified portions are removed. The process layer is etched using remaining portions of the carbon-containing silicon dioxide layer as an etch mask.
