Latest Patent Applications
Yu-Ting Guan's notable patent application is titled "METHOD OF PERFORMING SELECTIVE ETCH ON ARRAY SUBSTRATE." This application describes a method that includes a substrate and a component layer disposed on the substrate. The process involves mixing deionized water, hydrogen peroxide, and an acid, which can be sulfuric acid, hydrochloric acid, oxalic acid, or a combination thereof, to prepare a first solution. An alkoxy silane compound is then added to this first solution to create a second solution. The array substrate is immersed in the second solution to effectively remove the component layer, resulting in the formation of an aging second solution. Finally, the substrate is extracted from the aging second solution.
Conclusion
Yu-Ting Guan's work in selective etching technology showcases his innovative spirit and dedication to advancing the field. His contributions, particularly through his patent application, highlight the potential for improved methods in substrate processing.
