Abstract:
A production system for a semiconductor device comprising:means for forming a marker in a semiconductor film formed on an insulating surface; means for storing information concerning a pattern to be formed on the semiconductor film; means for specifying a region, which will be obtained after patterning of the semiconductor film and become an island-like semiconductor film, using the pattern information with reference to the marker and determining a region of the semiconductor film to be scanned with a laser light so that at least the region that will become the island-like semiconductor film is contained in the region to be scanned; a laser oscillation apparatus; an optical system for processing the laser light oscillated from the laser oscillation apparatus; means for controlling a position of a beam spot of the laser light on the semiconductor film so that the processed laser light is irradiated onto the determined region to be scanned with the laser light; and means for patterning the semiconductor film irradiated with the laser light in accordance with the pattern information.
