The lithographic exposure characteristic of amorphous silica (SiO 2) was investigated for 6.8 MeV 16O3+ ions. A programmable proximity aperture lithography (PPAL) technique was used for the ion beam exposure. After exposure, the exposed pattern was developed by selective etching in 4% v/v HF. Here,...
