Abstract
A laser annealing apparatus includes a plurality of lasers, a laser controller that controls the plurality of lasers such that a plurality of laser beams generated from the plurality of lasers is emitted at different timings, beam mixer optics that outputs a processing beam by mixing the plurality of laser beams of which output timings are adjusted, and focus optics that outputs the processing beam of which focus is adjusted. The processing beam includes a first processing laser beam having a first pulse, a second processing laser beam having a second pulse following the first pulse, and a third processing laser beam having a third pulse following the second pulse. A first peak of the first pulse is smaller than a second peak of the second pulse, and a third peak of the third pulse is smaller than the second peak.
