| Abstract: | The influence of total dose irradiation on hot-carrier reliability of 65 nm n-type metal-oxide-semiconductor fieldeffect transistors(nMOSFETs) is investigated.Experimental results show that hot-carrier degradations on irradiated narrow channel nMOSFETs are greater than those without irradiation.The reason is attributed to radiation-induced charge trapping in shallow trench isolation(STI).The electric field in the pinch-off region of the nMOSFET is enhanced by radiation-induced charge trapping in STI,resulting in a more severe hot-carrier effect. |
