Abstract:
A method of forming a liquid crystal display (LCD) on a substrate comprising the steps of;a) providing the substrate; b) depositing an amorphous silicon film at least 100 nm thick over the substrate; c) annealing at least one region of the amorphous silicon film using a sequence of laser pulses projected through a mask having a narrow slit to project a beamlet onto the surface of the amorphous silicon film to crystallize the amorphous silicon film as the beamlet is advanced over the surface of the amorphous silicon fun between successive laser pulses to produce at least one polycrystalline film region having a predominantly <100> crystallographic orientation; d) forming pixel structures over the amorphous silicon film; and e) forming circuit structures over at least one polycrystalline film region.
