A method of making a patterned metal oxide film includes jetting a sol-gel
solution on a substrate. The sol-gel solution is dried to form a gel
layer on the substrate. Portions of the gel layer are irradiated to
pattern the gel layer and to form exposed portions. Irradiation causes
the exposed portions of the gel layer to become at least one of
substantially condensed to an oxide, substantially densified,
substantially cured, and combinations thereof. The unexposed portions of
the gel layer are removed, thereby forming the patterned metal oxide
film.
