Abstract (in Japanese) (See Japanese page) 
(in English) Superconducting tunnel junction (STJ) detectors can theoretically achieve several ten times higher energy resolution than conventional semiconductor detectors and are expected to be applied to X-ray fluorescence analysis of trace light elements in next-generation power semiconductors such as SiC and GaN. However, since current STJs are integrated on Si substrate, signals generated by high-energy X-rays absorbed in the Si substrate overlap with characteristic X-ray peaks of the trace light elements, making trace light element analysis difficult. In order to prevent X-ray absorption directly under the STJs, we proposed a new structure in which the STJs are integrated on a freestanding membrane by removing the Si substrate directly under the STJs. In this study, we evaluated leakage current and fabrication yield of the new structure by current-voltage characteristics.
