Abstract
Aspects of embodiments of the present invention are directed toward a method of stacking disk-shaped substrates for polishing without using a centering shaft and an apparatus for implementing the method. A stack of disk-shaped substrates can be concentrically aligned without contacting the inside circumferential surfaces of the disk-shaped substrates by applying pressure to the outside edges of the disk-shaped substrates in different lateral directions.
