Total ionizing dose effects on MOS transistors fabricated in 0.18 µm CMOS technology

Total ionizing dose effects on transistors, fabricated in 0.18 μm CMOS technology are investigated. Radiation induced changes in NMOS and PMOS transistors parameters are discussed. Radiation induced narrow channel effect (RINCE) is demonstrated. Degree of influence of the bias conditions on the radiation response of the transistors in the given CMOS process is shown. Finally, impact of the devices electrical characteristics change on radiation hard design as well as outlook of further investigation activities is discussed.
