Latest Patents
One of Cho's latest patents is an etchant for conductive materials and a method of manufacturing a thin film transistor array panel using the same. This invention provides a method for creating a TFT array panel by forming a gate line with a gate electrode on an insulating substrate. The process involves sequentially depositing a gate insulating layer and a semiconductor layer on the gate line, followed by the formation of a drain electrode and a data line with a source electrode. The pixel electrode is then connected to the drain electrode. The etchant used in this process contains 65 wt % to 75 wt % of phosphoric acid, 0.5 wt % to 15 wt % of nitric acid, 2 wt % to 15 wt % of acetic acid, 0.1 wt % to 8.0 wt % of a potassium compound, and deionized water. This innovation simplifies the manufacturing process and reduces costs while ensuring high-quality TFT elements.
Another notable patent is for an etchant for signal wire and a method of manufacturing a thin film transistor array panel using this etchant. In this case, gate lines with a lower Al-Nd layer and an upper MoW layer, data lines with a MoW layer, and pixel electrodes with an IZO layer are patterned using a single etchant. The etchant comprises about 50-60% phosphoric acid, 6-10% nitric acid, 15-25% acetic acid, 2-5% stabilizer, and deionized water. The stabilizer includes oxy-hydride inorganic acid represented by M(OH)L, where M includes various elements, and L includes different functional groups.
