Abstract:
1. A thin film transistor comprising: a substrate; an active layer formed on the substrate, the active layer comprising a channel region, a source region and a drain region located at two lateral portions of the channel region; a gate insulating layer formed on the channel region; a nitride conductive layer located at the source region and the drain region respectively, the nitride conductive layer having an carrier concentration higher than that of the active layer; a gate electrode formed on the gate insulating layer; a source electrode formed on the nitride conductive layer and located above the source region; and a drain electrode formed on the nitride conductive layer and located above the drain region; wherein the nitride conductive layer is made of Al wherein a material of the active layer is selected from a group consisting of IGZO, IZO, AZO, GZO, ITO, GTO, ATO, TiOx and ZnO.
