Abstract
Effects of ion implantation on epitaxial CaF2 films grown on Si(100) substrates were investigated from the viewpoint of their application as an inorganic ion resists. It has been found that the etching rate of the CaF2 films in HCl acid is enhanced by a factor of about 4 by oxygen implantation with a dose of 1 × 1016 cm-2. It has also been found that optical properties of CaF2 films change, even in hydrogen-implanted samples with a dose of 2 × 1016 cm-2, after exposing the samples to an oxygen plasma.
