Abstract:
Provided are a thin film transistor having properties properly adjusted by adjusting crystallinity of a polycrystalline silicon, and a method of manufacturing the same. The silicon layer functioning as a channel layer of a TFT comprises an amorphous part, a first polycrystalline part and a second polycrystalline part. The first and second polycrystalline parts are formed by irradiating the silicon layer with laser beams (energy beams) through the mask comprising the shielding part for shielding the energy beams, the first transmission part for transmitting the energy beams and the second transmission part for transmitting the energy beams at a transmittance lower than that of the first transmission part. By the presence of the second polycrystalline part, properties of the TFT such as an electron mobility are properly adjusted. Further, properties of the TFT can be adjusted easily by adjusting the configuration of the mask.

Claim (Index 1):
A thin film transistor comprising:\n a substrate, a gate electrode disposed on the substrate, an insulating layer disposed on the gate electrode, a silicon layer disposed on the insulating layer, and a source electrode and a drain electrode disposed on the silicon layer, wherein the silicon layer comprises an amorphous part comprising an amorphous silicon, a first polycrystalline part comprising a polycrystalline silicon and a second polycrystalline part comprising a polycrystalline silicon having crystallinity lower than that of the first polycrystalline part.
