Appeal No. 96-3649
Application 08/344,509
?it is not adduceable from the references that such a film would
be a stoichiometric oxide film.? Thus appellants contend that
neither reference contains any suggestion that a stoichiometric
double metal oxide film is achievable, much less how one would
produce such a film. More specifically, appellants contend that
Sladek is specifically directed to processes and products ?in
which stoichiometry is not a consideration.? We do not agree
this interpretation of Sladek, however.
Initially, we point out that our review of Sladek is
hampered because the examiner has provided only the abstract of
this multipage publication for review. Nevertheless, the Sladek
abstract indicates that films of a family of metal oxide
materials were produced by passing water and alkoxide vapors in
nitrogen over a substrate in an isothermal rectangular reactor.
More specifically, Sladek indicates that films of Al O , Nb O ,2 3 25
Sb O , TiO , and ZrO were obtained as amorphous films which were2 3 2 2
annealed at high temperatures to cause crystallization with
increases in the refractive index. Clearly, the above films are
stoichiometric films i.e, chemical compounds having definite
proportions of the respective elements. Moreover, that
stoichiometry is a consideration of importance to Sladek is
implied by Sladek’s teaching that films described as VO and BOx x
