Appeal No. 96-1701
Application 08/190,211
Appealed claim 1 is representative and is reproduced below:
1. A method of forming a Josephson junction device
comprising the steps of:
forming a non-superconducting oxide film of Bi-Sr-
Cu-O compound by sequentially depositing at least Bi, Sr and Cu
on a magnesia substrate in a pattern;
and forming a superconducting oxide film of Bi-Sr-
Ca-Cu-O compound by sequentially depositing at least Bi, Sr, Ca
and Cu over the exposed part of said magnesia substrate and said
non-superconducting oxide film to form a tilt-boundary junction
between said superconducting oxide film on said magnesia
substrate and said superconducting oxide film on said non-
superconducting oxide film.
