Method and apparatus for laser annealing configurations of a beam

摘要

An object of the present invention is to provide a laser annealing method and apparatus capable of performing uniform beam emission. By means of the present invention, uniform beam application to a sample can be achieved because a linear cross-sectional configuration can be created in an optical system with a beam having a Gaussian distribution while areas of strong light intensity are avoided by rotating the beam from a laser light source at a prescribed angle by means of rotating means even when the beam pattern of the beam from the laser light source has a non-uniform intensity distribution.
