Latest Patents
Wakui holds a patent for a method of manufacturing a liquid crystal display device. This patent describes a liquid crystal color display of the active matrix type. The fabrication process begins with the deposition of a transparent conductive material, indium tin oxide (ITO), as a thin layer onto a glass plate. Following this, chromium is deposited as an opaque film onto the ITO layer. The two layers are selectively removed using a first mask pattern. An insulator layer consisting of Si₃N₄ is then deposited on the laminate within a reducing atmosphere of plasma. An I-type amorphous silicon layer is formed on the insulator layer, followed by the formation of a highly doped N-type amorphous silicon layer. The N-type silicon layer, the I-type silicon layer, and the silicon nitride layer are selectively removed. An aluminum layer is formed on the laminate and then selectively etched away. Finally, the chromium layer is selectively etched away to create gates, gate leads, pixel electrodes, sources, drains, and drain leads. This innovative method has the potential to improve the performance and reliability of LCD devices.
