Oxygen concentration present during free-radical photopolymerization of liquid photoresist thin films affects polymerization efficiency. In our photoresists, oxygen is both a sensitizer and a quencher, promoting radical formation as well as chain termination. Continuous diffusion of oxygen into the films keeps the oxygen concentrations steady despite oxygen depletion through quenching. We examine how polymerization responds to this complex competition of the oxygen's roles. Here we report our recent results on the effects of oxygen concentration on the polymerization threshold and polymer feature size in liquid photoresist thin films using acrylate monomer mixtures.
