Webinstance the thin films used in EUV lithography can significantly limit the ability to transfer the pattern to the substrate during the etch steps. To obviate the need for a hard-mask layer and thus the increasing of the process costs, the improvement of the resist etch resistance by using a MCR can be a reasonable approach to fix this issue.
