Superconducting Weak Links for Mixing at Millimeter-Wave Frequencies.
Abstract
A study is made for application of Josephson devices for millimeter-wave mixing. Technology for fabrication of small area silicon-coupled sandwich-type Josephson junctions is developed. A thin strip of superconducting metal film deposited on a degenerately doped silicon surface with a 0.1 - 0.3 micron gap cut across the film is shown to constitute a Josephson junction with certain significant advantages. A design of a Josephson junction two-dimensional array is made its properties are studied theoretically. A model for calculation of the action of a developer on a resist is devised. Calculations of the effect of thinning a substrate on the exposure of electron resists are made. (Author)
