Abstract:
A substrate support unit according to an example embodiment of the present inventive concept may include a support having an upper surface on which a substrate is disposed; a coupling ring on which an edge of the substrate is disposed, the coupling ring being having an annular shape, wherein the coupling ring is disposed on an edge of the support; and an arm part for raising and lowering the coupling ring and the substrate, wherein the arm part is disposed below the coupling ring and under a portion of the coupling ring, wherein the coupling ring has a first region disposed on the arm part and a second region disposed around the first region, wherein the first region has a thickness greater than that of the second region.
Abstract:
The present invention relates to a method for manufacturing an electrostatic chuck, and more specifically, to a method for manufacturing an electrostatic chuck with minimized temperature deviation. The method of the present invention includes: a step S10 of forming a metal layer by depositing metal on a lower portion of a base containing a ceramic material and provided with an ESC electrode at an upper portion thereof; and a step S20 of forming a heater electrode by forming a pattern on the metal layer using a photolithography process.
