Abstract:
A thin film transistor according to an embodiment of the present invention includes: a gate electrode supported by a substrate; a gate insulating layer covering the gate electrode; a silicon semiconductor layer being provided on the gate insulating layer and having a crystalline silicon region, the crystalline silicon region including a first region, a second region, and a channel region located between the first region and the second region, such that the channel region, the first region, and the second region overlap the gate electrode via the gate insulating layer; an insulating protection layer disposed on the silicon semiconductor layer so as to cover the channel region and allow the first region and the second region to be exposed; a source electrode electrically connected to the first region; and a drain electrode electrically connected to the second region. The channel region is higher in crystallinity than the first region and the second region.

Claim (Index 9):
A method of producing a thin film transistor, comprising:\n step (A) of providing a substrate, the substrate having formed on a surface thereof a gate electrode and a gate insulating layer covering the gate electrode; step (B) of forming a semiconductor film of amorphous silicon on the gate insulating layer; step (C) of forming an insulating film on the semiconductor film, and patterning the insulating film so as to form an insulating protection layer covering a portion of the semiconductor film to become a channel region; step (D) of irradiating the semiconductor film with laser light from above the insulating protection layer to crystallize the semiconductor film so that, in a region overlapping the gate electrode as viewed from a normal direction of the substrate, a portion of the semiconductor film that is covered by the insulating protection layer has a crystallinity which is higher than a crystallinity of a portion of the semiconductor film that is not covered by the insulating protection layer; and step (E) of forming a source electrode which is electrically connected to part of the portion of the semiconductor film that is not covered by the insulating protection layer and a drain electrode which is electrically connected to another part of the portion of the semiconductor film that is not covered by the insulating protection layer.
