Patent ID: 7964453

Claim:
A system for fabricating a semiconductor device including arrays of Thin Film Transistors (TFTs), the system comprising: a substrate; a continuous amorphous silicon (α-Si) film formed on a surface of said substrate; a positioning stage, said substrate with said a α-Si film formed thereon being secured to said positioning stage; a copper vapor laser generating pulsed visible laser radiation; data concerning a topology of said semiconductor device; a processor unit operatively coupled to said positioning stage and said copper vapor laser, said processing unit controlling relative disposition between said substrate and said pulsed visible laser radiation to sequentially direct said pulsed visible laser radiation to positions of localized areas on said α-Si film corresponding to locations of said TFTs, and intermittently actuate said copper vapor laser at selected time instances in correspondence with said disposition between said substrate and said pulsed visible laser radiation to irradiate only said positions of localized areas on said α-Si film corresponding to said locations of said TFTs; and an optical unit coupled to said copper vapor laser to condition said pulsed visible laser radiation into an homogenized and focused pulsed visible laser beam delivered to said localized areas and thereby crystallize said α-Si film sufficiently exclusively at said localized areas thereof.
