Polymer Interaction

The rate of photoacid generation is measured experimentally and it is demonstrated to depend on the interaction between polymer backbone and photoacid generator. The clearing volume per absorbed photon and per generated photoacid is also calculated and discussed in view of lithographic resolution and roughness.
