ABSTRACT:
A dry etching step during the manufacturing of a substrate for a liquid crystal display (LCD) device is improved by placing the substrate at a predetermined distance away from the lower electrode to prevent damage of the substrate due to electrostatic formed therebetween. An insulating tape attached on the lower electrode provides electrostatic protection between the substrate and the lower electrode, so that the substrate is properly lifted off the lower electrode via the lifting pins of the lower electrode without electrostatic interference.
