Appeal 2006-2449
Application 10/221,869
Appellants claim a granular magnetic thin film of non-oxidized
magnetic metal grains enclosed by insulating material. Appellants also
claim a method of manufacturing such a film.
Representative claims 3, 4, and 9 read as follows:
3. A granular magnetic thin film characterized in that an insulating
material is present around grain boundaries so as to enclose magnetic grains,
and that said magnetic grains are grains of non-oxidized magnetic metal.
4. A granular magnetic thin film characterized in that an insulating
material is present around grain boundaries so as to enclose magnetic grains
of a magnetic metal of a nature such that a spectral peak of an oxide of said
magnetic metal is not observable by a measurement made by an X-ray
photoelectron spectroscopy.
9. A method of manufacturing a granular magnetic thin film
characterized by the steps of preparing a magnetic metal target and an
insulating material target, respectively, sputtering said targets
simultaneously in a nonoxidizing atmosphere, and forming on a substrate a
thin film in which an insulating material is present around grain boundaries
so as to enclose magnetic grains.
The references set forth below are relied upon by the Examiner as
evidence of unpatentability.
