Abstract: A cover window manufacturing system comprises a laser irradiation apparatus including a stage configured to receive a substrate. A first laser module is disposed above the stage to provide a first laser beam to a top surface of the substrate. A controller controls a position of a focal point of the first laser beam on the substrate. An etching apparatus includes a chamber having an etching solution disposed therein. The etching apparatus is configured to receive the substrate processed by the laser irradiation apparatus and etch the substrate processed by the laser irradiation apparatus by immersion in the etching solution.
