Abstract:
This method includes a method for etch processing that allows the bias between isolated and nested structures/features to be adjusted, correcting for a process wherein the isolated structures/features need to be smaller than the nested structures/features and wherein the nested structures/features need to be reduced relative to the isolated structures/features, while allowing for the critical control of trimming.
