Latest Patents

One of Takeichi's latest patents is titled "Thin film transistor formed by an etching process with high anisotropy." This invention discloses a thin film transistor and a process for forming it using a high anisotropy etching process. The thin film transistor comprises a transistor element that includes a gate electrode, a gate insulating layer, a semiconductor layer, and source and drain electrodes. Additionally, a passivation layer is deposited on these layers, featuring first openings for contact holes. An interlayer insulator extends along with the passivation layer and has second openings for the contact holes, ensuring that the first and second openings are aligned over the substrate. An electrical conductive layer is then deposited on the inner wall of the contact hole, which is formed by the tapered openings created through the anisotropic etching process.

Another notable patent is for a "liquid crystal display device and method for fabricating the same." This invention includes a first transparent substrate and a second transparent substrate, arranged such that their first surfaces face each other, enclosing a liquid crystal material between them. A pixel array is formed on the surfaces of the substrates, allowing data signals to be applied through data lines to the pixel regions.
