Patent ID: 8021936

Claim:
A method of manufacturing a thin film transistor, the method comprising: providing a transparent substrate; forming an insulating layer on the transparent substrate, the insulating layer being in a second region of the transparent substrate; forming a monocrystalline silicon layer on the insulating layer; forming a gate insulating layer and a gate electrode on the monocrystalline silicon layer; and implanting a dopant into the monocrystalline silicon layer around the gate electrode, wherein forming the monocrystalline silicon layer on the insulating layer includes: forming a first monocrystalline silicon layer on a first region of the transparent substrate, the first region adjacent to the second region, forming an amorphous silicon layer on the first monocrystalline layer and the insulating layer, transforming the amorphous silicon layer into a second monocrystalline silicon layer, and patterning the second monocrystalline silicon layer to make an island-type second monocrystalline silicon layer on the insulating layer.
