A decompression vessel(210) is formed to define an internal space for generating plasma. A plasma generator(220) is formed to generate the plasma. An upper plate(230) is positioned under the plasma generator. The upper plate includes at least two or more dielectric plates(235).

Abstract:
PURPOSE: A method for selectively removing a polyimide organic alignment layer applied to a glass substrate where a negative photoresist is formed by using plasma while reproducing the glass substrate is provided to selectively remove a polyimide organic alignment layer only applied to a negative photoresist by using dry plasma, thereby effectively reproducing a substrate. CONSTITUTION: A polyimide organic alignment layer(102) is applied to a negative photoresist forming glass substrate. The negative photoresist forming glass substrate is injected into a reaction chamber(10) while maintaining pressure at 100 to 900mTorr. The pressure is maintained by injecting O2/N2 mixed gases within the reaction chamber(10). Plasma is generated by applying power to an electrode of a plasma reaction device. The polyimide organic alignment layer(102) is selectively dissolved.
