A new effective fabrication module was developed to mediate the problem of the low yield of Indium-tin-oxide (ITO) nanostructures deposition uses micro electroremoval technology and a design of twins-cylinder tool as a precision etching process to remove the defective Indium-tin-oxide (ITO) from the optical PET diaphragm surfaces of digital-paper displays. For the removal-process, a small gap width between the negative electrode and the workpiece (optical PET diaphragm) surface corresponds to a higher removal rate for the ITO. A small diameter of the anode or a small diameter of the cathode of the twins-cylinder tool provides large electric current density and takes less time for the same amount (20 nm) of ITO removal. High rotational speed of the twins-cylinder tool the discharge mobility and results in improving the removal effect. Providing enough electrical power can uses fast feed rate of the optical PET diaphragm combined with a fast removal rate for ITO. With increasing in current rating, pulsed direct current can improve the effect of dregs discharge and is advantageous to associate with the fast feed rate of the optical PET diaphragm. By establishing a recycling process using the ultra-precise removal of thin-film nanostructures, through the micro electroremoval and the twins-cylinder electrodes requires only a short period of time to remove the ITO thin-film easily and cleanly. The optoelectronic semiconductor industry can effectively recycle defective products, minimizing both production costs and pollution.
