Abstract
Microcircuits composed of a plurality of alternating conducting and insulating regions are formed in a substrate of an organic quasi-unidimensional conductor such as .DELTA..sup.2,2 bi-4,5-dimethyl-1,3-diselenolylidene upon irradiation of the substrate with a precise beam of electrons having an energy of at least 1 keV, preferably at least 8 keV, which forms the insulating regions. When exposed to cryogenic temperatures the non-irradated conducting regions become super conducting. Using electron beam irradiations, sub-micronic resolution as low as 100 .ANG. can be achieved. Microcircuits having Josephson junctions and superconducting quantum interference devices are described.
