Abstract
A reverse short-channel effect, manifested by an increase in the transistor threshold voltage as the channel length is reduced, is observed in conventional metal-induced laterally crystallized thin-film transistors. Such an effect has not been observed in regular solid phase crystallized thin-film transistors and can be eliminated by a brief hydrogen plasma treatment.
