ABSTRACT:
A method of etching a substrate is provided. The method of etching a substrate includes transferring a pattern into the substrate using a double patterned amorphous carbon layer on the substrate as a hardmask. Optionally, a non-carbon based layer is deposited on the amorphous carbon layer as a capping layer before the pattern is transferred into the substrate.
