Abstract:
A thin film transistor comprising:a substrate having an insulating surface; a channel region formed on said insulating surface comprising an intrinsic non-single crystal semiconductor material; a pair of source and drain regions with said channel region therebetween, said source and drain regions comprising a non-single crystal semiconductor material having an impurity conductivity type; a gate insulating film comprising a nitride formed on said channel region so that the portion of the channel region in direct contact with the gate insulating film is said intrinsic non-single crystal semiconductor material; a gate electrode formed on said gate insulating layer, wherein said source, drain and channel regions are doped with a recombination center neutralizer selected from the group consisting of H, a halogen and a combination thereof, and said gate insulating film extends beyond said channel region to cover junctions between said channel region and said source and drain regions.
