Title: Manufacture of josephson junction
Inventor: AOYANAGI MASAHIRO
IPC: H01L39/24
Filed: 1985-07-17
Abstract: PURPOSE:To reduce the variability of Josephson critical currents by spreading a lower electrode layer consisting of an Nb compound superconductor on a substrate and etching the surface by sputtering with a low self-applied bias voltage, followed by discharge oxidation with the same degree of self-applied bias voltage and then spreading an upper electrode layer on that. CONSTITUTION:After spreading a lower electrode layer 2 consisting of an Nb compound superconductor on a substrate 1, the surface is subjected to sputter etching for several decade min with self-applied bias voltage of several decade V, thereby weakening the combination state among atoms from the surface to a certain depth of the layer 2. Subsequently, only the surface layer 3 which has been etched at a low self-applied bias voltage of the same degree as the above voltage is discharge-oxidized to be changed into an oxide layer 4, on which an upper electrode layer 5 is deposited to compose a Josephson junction. Thus, the junction is made uniform and the variability of critical current can be reduced to about + or -7% in intervals of 1cm.
