Abstract

A crystallization apparatus and method that is adapted to crystallize a semiconductor using a non-vacuum process. In the apparatus and method, laser beams are irradiated onto a substrate to grow a crystal unilaterally from the side surface of the substrate. Grain boundaries are minimized under the air atmosphere, so that a crystallization of the substrate can be made in a non-vacuum state to improve the throughput.
