Abstract: A supporting unit is provided. The supporting unit includes a body, an alignment member, at least one sensor, and a controller. The body has a top surface supporting a target object. The alignment member is disposed in the body and adjusts a position of the target object. The sensor senses the position of the target object. The controller controls the alignment member and the sensor member. The alignment member includes a magnet that adjusts the position of the target object according to an electromagnetic force; and a coil that applies the electromagnetic force to the magnet.

Abstract: An optical apparatus and a manufacturing method using the optical apparatus are disclosed. The optical apparatus includes a stage supporting a substrate, first optical systems providing a first light onto the substrate, a gantry supporting the first optical systems to transfer them on the stage, and second optical systems disposed between the gantry and the stage and detecting displacement of the first optical systems. Each of the second optical systems includes a beam source generating a second light different with the first light, and sensor arrays for sensing the second light provided to the first optical systems to detect displacement of the first optical systems.
