ABSTRACT:
A method for directing a light beam to a substrate and an apparatus to do the same. A single light beam is directed to a diffractive element. The diffractive element diffracts the single light beam to form a plurality of light beams. A controller generates a first control signal for controlling a digital micromirror device which selectively directs each of the plurality of light beams toward or away from the substrate. A lens focuses each selectively directed beam onto the substrate.
