Latest Patents

One of Chae’s listed patent titles is “Thin Film Transistor Array Panel and Method of Manufacturing the Same.” The described method covers forming a polysilicon semiconductor layer on an insulating substrate, then adding the gate insulation, gate electrode, doped source and drain regions, interlayer insulation, source and drain electrodes, passivation layer, and pixel electrode.

The method also addresses alignment during fabrication. It forms a first alignment key alongside a selected panel layer and uses photolithography with a photoresist pattern as an etch mask. A second alignment key, formed at the same layer as the photoresist pattern, completely covers the first alignment key. This approach focuses on alignment features within the manufacturing process.
