Abstract: A major problem for the implementation of microelectroremoval is the cost and the design of the tool electrode. An effective nanoscale processing for yield improvement was developed using microelectroremoval and a designed twin-cylinder tool as a precision reclamation retrieval system to remove the defective indium tin oxide (ITO) thin-film nanostructures from the optical PET surfaces of digital paper. By establishing a recycling process using the ultra-precise removal of nanostructures, the optoelectronic semiconductor industry can effectively recycle defective products, minimizing both production costs and pollution. In the current experiment, small thickness of the anode, combined with enough electric power and provided a larger discharge space, and better removal effect. A large diameter of the cylinder acthode accompanied by a small gap-width between the cathode and the workpiece, takes less time to do the same amount of ITO removal. A higher rate of removal of the defective ITO nanostructures corresponds to high temperature, a large electrolyte flow rate with a high rotational speed of the electrodes. A faster feed rate of color filters combined with a higher electric current produces a fast removal rate. A small edge angle of the anode also provides higher current density, which is advantageous for ITO removal.

Abstract: A new triangular-shape designed tool as a cathode in microelectromechanical etching process is a precision nanoscale production of a reclamation system of Indium tin oxide (ITO) thin-films defects removal from optoelectronic flat panel displays’ color filter surface is demonstrated in the current study. Through the ultra-precise removal of the thin-film nanostructure, the optoelectronic semiconductor industry can effectively reclaim defective products, reducing production costs. In the current experiment, a large size triangular shape cathode is accompanied by a small gap-width between the cathode and the workpiece takes less time for the same amount of ITO removal. A higher feed rate of displays’ color filter or a small end radius of the cathode combined with enough electric power produces fast machining. Pulsed direct current can improve the effect of dregs discharge and is advantageous in association with a fast workpiece feed rate. However, it raises the current rating. A large flow rate of the electrolyte corresponds to a higher removal rate for the ITO nanostructure. The electrochemical etching just needs a short time to make the ITO remove removal easy and clean.
