Abstract:
1. A process for consolidating resist structures, which comprises the following method steps: applying a resist to a substrate, said resist being a chemically amplified resist, including: a film-forming polymer having a first monomer and a second monomer, and wherein: a photoacid generator; and a solvent; drying the resist to form a dried resist; exposing with radiation having a wavelength of less than 200 nm the dried resist to form an exposed resist containing a latent image; heating the exposed resist to a first temperature, to thereby transform the latent image into a chemical profile, and liberating polar groups on the polymer; developing the resist with an aqueous alkaline developer, to detach areas of the chemical profile containing polar groups of the polymer from the substrate, to form a structured resist; applying an amplifying agent to the structured resist; and washing off excessive amplifying agent.
