Patent ID: 7704807

Claim:
A method of fabricating a multi-channel type thin film transistor, comprising: forming a plurality of active layers on a substrate extending along a first direction, the plurality of active layers extend parallel to and spaced apart from each other, each of the plurality of active layers including a channel region overlapped with a gate electrode, a source region in one side of the channel region, and a drain region in another side of the channel region; forming a gate-insulating layer on the plurality of active layers; forming the gate electrode on the gate-insulating layer extending along a second direction crossing the first direction, overlapping widths of the gate electrode with the adjacent active layers are different from each other and channel lengths of the adjacent channel regions are different from each other; doping the source and drain regions; and forming source and drain electrodes over the gate electrode extending along the second direction, the source and drain electrodes are spaced apart from each other with respect to the gate electrode and are connected to the source and drain regions.
