Abstract

Thin films (e.g. less than 100 nm thick) of a metal oxide material can be deposited on a variety of hydrophilic substrates by hydrolysis. Deposition is achieved by reacting a vapor of an appropriate metal-containing compound with water at or near the substrate's surface. The resulting deposited film can serve a variety of uses, for example, as a photo-resist in micro-electronics or in any area where protective films are useful, such as the passivation of ternary metal oxide superconductors.
