Patent ID: 7682951

Claim:
A method for fabricating a polysilicon layer, the method comprising: providing a substrate, and forming an amorphous silicon layer over the substrate; providing an excimer laser generator for generating pulse excimer laser beams collectively having the shape of a generally rectangular shaft, and melting a first area of the amorphous silicon layer with the pulse excimer laser beams; moving the excimer laser generator a distance to melt a second area of the amorphous silicon layer, the second melted area spaced a short distance away from the first melted area of the amorphous silicon layer; and forming at least a subsequent third melted area spaced a short distance away from the second melted area, with each such subsequent melted area being spaced a short distance away from the immediately preceding melted area, wherein each subsequent melted area and the immediately preceding melted area are separated by an unmelted interval area.
