<p>Disclosed are an aligner and a wafer sorting device using the same. The disclosed aligner comprises: a body forming the appearance of the aligner; an alignment unit installed on the body to rotate or horizontally move a wafer; a displacement detection unit measuring the horizontal displacement of the wafer in accordance with the rotation of the wafer and a notch part formed on the wafer; and a checking unit checking the mounting state of the wafer mounted on the alignment unit. The alignment unit rotates or horizontally moves the wafer in accordance with the position of the notch part and the displacement corresponding to the rotational angle of the wafer in order for the wafer to be regularly placed on a predetermined position.</p> |
