Abstract:
1. A plasma chemical reactor comprising: a chamber for providing a plasma reaction space; and a cathode assembly coupled at one side to a wall surface of the chamber and supporting a substrate at the other side such that the substrate is positioned at a center inside the chamber, and installed to enable height adjustment such that the substrate can maintain a horizontal state, wherein the wall surface of the chamber is substantially perpendicular to a horizontal direction of the horizontal state of the substrate, wherein the cathode assembly comprises: a lower electrode installed within the chamber and safely mounting a substrate; a support body installed at one side of the chamber such that the lower electrode can be positioned at a center within the chamber, and supporting the lower electrode; and a balance adjustment unit supporting the support body and installed to enable height adjustment such that a balance of the lower electrode can be adjusted, wherein the balance adjustment unit supports a bottom surface of the electrode base and is screw coupled on a circumference surface of its lower end part to a lower part of the chamber to enable height adjustment, wherein the balance adjustment unit is plurally provided at equal interval along an outer circumference of a bottom surface of the electrode base.
