Abstract:
1. A method of forming a photoresist-comprising pattern on a substrate, comprising: forming a patterned first photoresist over a substrate, the patterned first photoresist comprising spaced first masking shields in at least one cross section; exposing the first masking shields to a fluorine-containing plasma to form a hydrogen and fluorine-containing organic polymer coating about outermost surfaces of the first masking shields; depositing a second photoresist over and in direct physical touching contact with the hydrogen and fluorine-containing organic polymer coating received about the first masking shields; and exposing the second photoresist which is in direct physical touching contact with the hydrogen and fluorine-containing organic polymer coating to a pattern of actinic energy and thereafter forming spaced second masking shields in the one cross section which comprise the second photoresist and correspond to the actinic energy pattern, the first and second masking shields together comprising a photoresist-comprising pattern on the substrate.
