Abstract
A method for thinning a substrate is provided. The method includes at least the following steps. A substrate is disposed on a carrying surface of a chuck, where a first liquid supply unit surrounds the chuck to form a frame of the chuck, and an outlet of the first liquid supply unit is disposed aside the carrying surface of the chuck. A first liquid flows from a bottom of the frame to the outlet and discharges to fill a gap between the substrate and the carrying surface of the chuck. The substrate is thinned during the gap is filled.
