Abstract: In the aim of helping the development of robots used in radiological emergency preparedness and response,the TID effects on the threshold voltage shift(ΔVth) of different kinds of MOSFET with different geometry and different scaling technology was compared.The different gate width and the length dependent between bulk CMOS process and NW MOSFET is noticed.And the TID effects on ΔVth of several kinds of new devices such as Ge-channel and GaN channel MOSFETs and MOSFETs with new layout geometry are described which can be investigated more deeply.In addition,TCAD simulation is introduced to be used in both mechanism investigation and modeling verification.

Key words: total ionizing dose (TID), threshold voltage shift, MOSFET, TCAD
