发明名称 FET RADIATION MONITOR
摘要 A semiconductor device includes a semiconductor substrate; a buried insulator layer disposed on the semiconductor substrate, the buried insulator layer configured to retain an amount of charge in a plurality of charge traps in response to a radiation exposure by the semiconductor device; a semiconductor layer disposed on the buried insulating layer; a second insulator layer disposed on the semiconductor layer; a gate conducting layer disposed on the second insulator layer; and one or more side contacts electrically connected to the semiconductor layer. A method for radiation monitoring, the method includes applying a backgate voltage to a radiation monitor, the radiation monitor comprising a field effect transistor (FET); exposing the radiation monitor to radiation; determining a change in a threshold voltage of the radiation monitor; and determining an amount of radiation exposure based on the change in threshold voltage.
