Latest Patents

Woong Kwon Kim holds a patent for a "Method for manufacturing a substrate of a liquid crystal display device." This method prevents defective patterning of pixel electrodes and improves the aperture ratio of pixels by simplifying the steps involved in manufacturing an LCD substrate. A protection layer is formed on the substrate, which includes a light developable organic (BCB) layer. This layer is patterned directly by exposure using a mask, rather than through traditional photo resist methods. The remaining portion of the light developable organic layer on the bottom part of contact holes is etched using a gate insulating layer. The etching process is performed partially to expose the surface of the gate pad using a plasma gas mixture of approximately 85% CF and 15% O.
