Abstract

Provided are an electrostatic chuck, which is manufactured to be reusable by removing a part of a dielectric layer except for a DC electrode and a heater electrode and depositing a new dielectric layer thereon, and a method for manufacturing the electrostatic chuck, and a substrate processing system including the electrostatic chuck. The method for manufacturing the electrostatic chuck includes, after using an electrostatic chuck, removing a portion of an upper part of a first dielectric layer of the electrostatic chuck where an electrode is not formed, depositing a second dielectric layer on the first dielectric layer from which the portion of the upper part has been removed, and patterning the second dielectric layer to enable reuse of the electrostatic chuck.
