Abstract

Degradation in low-temperature poly-Si TFT devices was studied for high-field stressing hot-carrier stressing as well as gamma radiation stressing. It was found that degradation is dominated by electron trapping in the gate oxide that causes a parallel rightward shift in the transfer curves. The other probable mechanisms involved include generation of mid-gap defects in the bulk polysilicon and creation of mid-gap defects in the bulk polysilicon and creation of interface states at the Si/SiO₂ interface.
