UBM (UNDER BUMP METAL) ELECTRODE STRUCTURE FOR RADIATION DETECTOR, RADIATION DETECTOR AND PRODUCTION METHOD THEREOF

摘要

An UBM electrode structure body for a radiation detector and a radiation detector arranged with the UBM electrode structure body are provided for suppressing peeling and having high electrode adhesion. In addition, a manufacturing method of an UBM electrode structure body for a radiation detector and a manufacturing method of a radiation detector using the UBM electrode structure body are provided in which peeling does not occur during UBM structure formation, a solder bonding process or bonding of a signal line to a Pt layer. The UBM electrode structure body for a radiation detector of the present invention is arranged with a CdTe substrate or CdZnTe substrate and a Pt electrode layer arranged on the CdTe substrate or CdZnTe substrate, adhesion of the Pt electrode layer with respect to the CdTe substrate or the CdZnTe substrate being 0.5 N/cm or more.
