HIGH CRITICAL-TEMPERATURE SUPERCONDUCTING THIN-FILMS FOR MICROELECTRONICS

High critical temperature superconductors (HTCS) are very promising fo r applications in microelectronics due to the control of high quality epitaxial thin films, in spite of a number of specific constraints. Ac tive and passive devices are already available in various laboratories , prooving that applications are actually expected soon. We report her e on the interest of HTCS thin films, on preparation processes includi ng materials and substrates choice, and also on characterization metho ds which are required in order to chek the quality of the samples. Fin ally some illustrative examples of applications are presented.
