Abstract

[$SiO_2$] film coated as a passivation layer for YBCO based electronic devices is investigated by measuring the micro wave properties of micro strip line resonators. The $SiO_2$ film coated resonators are compared with coated resonators for two degradation conditions, a $200^{\circ}C$ annealing in air and an exposure to air at $85^{\circ}C\;85\%$ relative humidity. The $SiO_2$ film reduces the YBCO thin film degradation caused by oxygen stoichiometry change and reaction with water.
