Abstract
Using 2MAdMA(2-Metyl-2-Adamantylmethacrylate), 2MAdAA(2-Metyl- 2-Adamantylacrylate), GBLMA((gamma) -butyrolactone methacrylate), GBLAA((gamma) -butyrolactone acrylate) monomers, 4 types of copolymers, 2MAdMA/GBLMA, 2MAdMA/GBLAA, 2MAdAA/GBLMA, 2MAdAA/GBLAA resins were prepared. The same PAG formulation was applied to these resins to make ArF resist samples. Resolution capability, dry-etching resistance were evaluated. From the result, it can be concluded that 2MAdAA/GBLMA resin system has the best balance in dry etching resistance, resolution and sensitivity.
