Abstract:This paper presents the design methodology, fabrication and characterization of flip-chip bonded MEMS capacitor for tuning high temperature superconductive resonator. Because the main issue of MEMS capacitor integrated with high temperature superconductor (HTS) is high driving voltage due to accumulated thermal stress, a methodology to decrease the thermal stress is discussed. In this work, the thermal stress can be reduced to several MPa, and driving voltage is about 40V. To avoid degradation of HTS thin film… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
