A three-component positive working resist composed of an acrylate polymer, vinyl ether cross-linker, and photoacid generator was evaluated for vacuum UV lithography. The vinyl ether cross-linker using tricyclodecyl group of alicyclic compound has a high transparency. This resist system shows a relatively high sensitivity and has a good profiling by irradiation using 193 nm light from an ArF excimer laser. Moreover, we found that these cross-linking type resists have advantages with respect to its resist properties such as the acid diffusion and the dry etching resistance.
