WebbPhotosensitive polymers and their use in photoresists for photolithographic processes are disclosed. The polymers are copolymers, with at least one monomer that includes pendant polycyclic aromatic groups and a second monomer that includes an acidic leaving group (ALG). The polymers have high resistance to etching and high development contrast. WebbPhotoresist descum is the process of removing the photoresist residual in the open trenches or holes after the lithography and developing steps. The photoresist residual is usually on the nanometer scale. If the residual is not removed, it can cause a uniformity issue for the subsequent etching process.
