WebPhotosensitive 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.

Web25 okt. 2013 · Lithography: Resolution and Immersion Lithography (from Ancient Greek λίθος, lithos 'stone', and γράφειν, graphein 'to write') is a planographic method of printing originally based on the immiscibility of oil and water. The printing is from a stone (lithographic limestone) or a metal plate with a smooth surface. It was invented in 1796 by the German author and actor Alois Senefelder and was initially used mostly for musical scores and map…
