Abstract

Methods for thermal treatment on a semiconductor device is disclosed. One method includes obtaining a pattern of a treatment area having amorphous silicon, aligning a laser beam with the treatment area, the laser beam in a focused laser spot having a spot area equal to or greater than the treatment area, and performing a laser anneal on the treatment area by emitting the laser beam towards the treatment area for a treatment period.
