Abstract
Positioning devices and positioning methods are provided. The positioning device includes a laser source and an optical assembly. The optical assembly is configured to direct a laser beam projected from the laser source toward a floor and a ceiling of a semiconductor fabrication facility to generate a first laser line on the floor and a second laser line on the ceiling. The first laser line and the second laser line are parallel to and aligned with each other when viewed in a direction perpendicular to the floor and the ceiling. Accordingly, the first laser line and the second laser line can be used to align a semiconductor tool and an overhead hoist transport system in the semiconductor fabrication facility.
