More Information
Summary:A dry etching device which can be used to etch products or used in processes regardless of materials and exhibits an excellent accuracy, and a method for controlling the same. The dry etching device includes: an anode part; a cathode part disposed at an upper side of the anode part and facing the anode part, receiving bi-directional voltage power in which polarity of a voltage alternates between a positive voltage and a negative voltage depending on time, and spaced apart from the anode part; a leveling part disposed in close contact with a surface of the cathode part facing the anode part, and for positioning a work-piece in a flat state; a holding part for holding the work-piece and the leveling part to the surface of the cathode part facing the anode part; and a bi-directional voltage power supplier for applying the bi-directional voltage power to the cathode part.
