A method for performing a laser crystallization is provided. The method includes generating a laser beam, refracting the laser beam to uniformize an intensity of the laser beam at a focal plane of the laser beam. The laser beam whose intensity is uniformized is applied into an object substrate mounted with a stage.

Method for performing laser crystallization

Apparatus for uniformizing light amount distribution by shaking line beams along a longitudinal axis direction is provided. The apparatus includes a mirror mount, a mirror, an actuator, and a deformation member. The mirror fixed to the mirror mount and includes a reflective surface. The actuator is disposed at a distance from the mirror mount and configured to repeat expansion and contraction along a first direction. The deformation member includes a plurality of blocks connected to each other by flexible joints and is coupled to the actuator and the mirror mount. The deformation member is configured to change a displacement in the first direction due to operation of the actuator to a displacement in a second direction that crosses the first direction, amplify the changed displacement, and transmit the amplified displacement to the mirror mount.

Optical module for laser beam shaking

A silicon crystallization system includes a vibration device for vibrating a linear laser beam along a longer-axis direction of the linear laser beam. A vibration frequency at which the laser beam is vibrated is periodically generated and randomly changes within a predetermined range.
