Life of the patent
20 dated eventsAbstract
Provided is a sputtering apparatus which deposits a metal catalyst on an amorphous silicon layer at an extremely low concentration in order to crystallize amorphous silicon, and particularly minimizes non-uniformity of the metal catalyst caused by a pre-sputtering process without reducing process efficiency. This sputtering apparatus improves the uniformity of the metal catalyst deposited on the amorphous silicon layer at an extremely low concentration. The sputtering apparatus includes a process chamber having first and second regions, a metal target located inside the process chamber, a target transfer unit moving the metal target and having a first shield for controlling a traveling direction of a metal catalyst discharged from the metal target, and a substrate holder disposed in the second region to be capable of facing the metal target. A distance difference between a linear distance, which is a distance between a substrate loaded on the substrate holder and the metal target, and a length of the first shield is less than 3 cm.
