Abstract:
A thin film transistor, a method for fabricating the same, a display device, and an exposure device are disclosed. The method comprises: patterning a source and drain layer by using a single slit mask and an exposure machine, to form a source, a drain, and an active region of the thin film transistor; wherein a pattern resolution of the single slit mask is not larger than a resolution of the exposure machine to form a groove shaped exposure pattern, wherein the groove shaped exposure pattern corresponds to the active region.

Claim (Index 2):
The method of  claim 1 , wherein the step of patterning the source and drain layer by using the single slit mask and the exposure machine, to form the source, the drain, and the active region of the thin film transistor comprises:\n coating a first photoresist on the source and drain layer; exposing and developing the first photoresist by using the single slit mask and the exposure machine according to a size of the source and the drain, so that the resulting first photoresist on the source and drain layer forms a groove shaped exposure pattern; ashing the first photoresist at a bottom of the groove shaped exposure pattern, to reveal the source and drain layer; wet etching the source and drain layer to form the source and the drain, and to reveal an active layer at a position to which the groove shaped exposure pattern corresponds to form the active region of the thin film transistor; and removing the remaining first photoresist.
