Methods for enhancing resolution of a chemically amplified photoresist |
摘要 |
Methods are provided for enhancing resolution of a chemically amplified photoresist. A film comprising a photoacid generator and a polymer comprising functional groups bonded to protecting moieties is deposited on a substrate. The film is exposed to patterned radiation. The patterned radiation results in protonation of a portion of the functional groups and the formation of a latent image within the film. The bonds between the protonated functional groups and the protecting moieties are selectively excited with non-thermal energy having a wavelength spectrum that resonantly cleaves the bonds.
