Claim 1
Independent Claim
114 words
THE METHOD OF FABRICATING A THIN FILM GATE CONDUCTOR HAVING A RELATIVELY ABRUPT MAGNETIC TRANSITION BETWEEN THE SUPERCONDUCTING AND RESISTIVE CONDUCTION STATES COMPRISING THE STEPS OF FORMING A THIN FILM OF SUPERCONDUCTIVE MATERIAL UPON AN OUTGASSED SUBSTRATE WITHIN AN EVACUATED CHAMBER BY THERMALLY EVAPORTATING SAID SUPERCONDUCTIVE MATERIAL THROUGH A PATTERN DEFINING MASK; SAID THIN FILM THEREBY INCLUDING A CENTER PROTION AND A PAIR OF EDGE PROTIONS; AND SUBJECTING SAID THIN FILM TO AN ELEVATED TEMPERATURE BELOW THE MELTING TEMPERATURE OF SAID CENTER PORTION FOR A TIME SUFFICIENT ONLY TO ELECTRICALLY DISASSOCIATE SAID PAIR OF EDGE PORTIONS FROM SAID CENTER PROTION, SAID TIME BEING INSUFFICIENT TO ALLOW IMPURITIES TO BE ABSORBED BY SAID CENTER PORTION.
