  • Patent number: 9005998
    Abstract: A laser annealing apparatus reduces laser annealing time and has a simple configuration. A laser annealing method is used to manufacture a display apparatus. The laser annealing apparatus includes a mounting unit, a substrate mounted on the mounting unit, first and second driving modules installed on the mounting unit and adjusting locations of first and second mark masks to be placed on a part of the substrate, first and second image modules that may obtain image data regarding the first and second mark masks to be location-adjusted by first and second driving modules, and a laser module that radiates a laser beam to the substrate and changes at least a part of an amorphous silicon layer of the substrate to crystalline silicon.

  • Publication number: 20140360987
    Abstract: A laser apparatus includes: a laser which selectively irradiates a laser beam to a portion of a target based on a laser driving voltage, where an intensity of the laser beam is substantially stabilized within about 10 nanoseconds; a stage which controls a relative location between the target and the laser based on a stage driving voltage; and a controller which applies the stage driving voltage to the stage, and applies the laser driving voltage to the laser
