Abstract:
A thin film transistor and a method of fabricating the same are provided. The thin film transistor includes a channel layer, a source, a drain, an insulating layer and a gate. The channel layer is disposed on a substrate. The source and the drain are disposed separately on the channel layer. The insulating layer covers the source, the drain and the channel layer. The gate is disposed on the insulating layer, wherein two opposite sidewalls of the channel layer are respectively aligned to a sidewall of the source distant to the drain and a sidewall of the drain distant to the source. The thin film transistor of the invention improves the precision of alignment in the fabricating process, such that the film transistor has an excellent quality.

Claim (Index 6):
A method of fabricating a thin film transistor, comprising:\n forming a channel material layer on a substrate; covering a conductive material layer on the channel material layer to form a stacked layer on the substrate; removing a portion of the stacked layer to form an alignment mark and a patterned stacked layer separate from each other, wherein the patterned stacked layer comprises a channel layer and a conductive layer formed on the channel layer; patterning the conductive layer for forming a source and a drain separate from each other, wherein the source and the drain expose a portion of the channel layer; covering an insulating layer on the source, the drain and the channel layer; and forming a gate on the insulating layer.
