Abstract

With an objective to perform survey and forecast on the future of superconducting elements, collection of latest technological information and analyses of technological trends were carried out by members of the Technology Forecast and Research Committee. This paper summarizes the achievements therein. It was discovered that the Josephson element using an Al{sub 2}O{sub 3} barrier and an Nb electrode shows excellent characteristics with very good reproducibility. Trial fabrication of a four-bit micro processor was recently executed successfully by the SQUID gate using the above element. On the other hand, application of devices using high-temperature superconductors has not come out with an achievement. Although a large number of achievements have been released on mono-crystalline thin films that show good characteristics, development of substrates and barrier materials is still needed for device configuration. The method for manufacturing metal-based superconducting films has been established nearly completely as an elementary technology to develop the superconducting elements. However, making thinner the high-temperature superconducting films having been discovered recently is encountering a number of inherent problems, whereas the present stage is such that experimental discussions are being made. The process technologies, simulation, and evaluation technologies are basically the same as those for the metallic systems even  More>>
