Description

The SOI technology is very attractive realizing high-performance monolithic pixel devices. The TID tolerance has been a mojor issue in applicatons, as the positive charges accumulated in the oxide layers deteriorate the performance of the nearby FETs. With use of the innovative double-SOI, the TID effect is shown to be compensated by applying negative voltages to the middle layer. We fabricated a pixel sensor for demonstration and succeeded in operating the pixel device irradiated up to 1 MGy.
