Abstract
A carrier recycling process designed to recycle carriers discarded after use for a certain period of time. The carrier recycling process includes dipping a carrier to be discarded in an organic solvent to remove a bond and to separate a body and an insert from each other, securing a surface roughness of one side surface of the body from which the insert has been separated, depositing a diamond-like-carbon (DLC) coating layer on the one side surface of the body having the secured surface roughness using a PECVD process, and coupling the insert to a circumference of the body having the DLC coating layer deposited thereon.
