Thin film transistor pixel cell for a display device |
摘要 |
<p>A pixel cell has a thin film transistor structure formed on a substrate. A signal conductor is patterned on the thin film transistor structure, and a first patterned layer of a transparent conductive material covers the signal conductor. The first patterned layer provides a pattern employed in etching a channel region of the thin film transistor structure. A dielectric layer is formed over the pixel cell and includes a via hole down to the first patterned layer of the transparent conductive material. A second layer of transparent conductive material extends through the via hole to contact the first patterned layer wherein the second layer is self-aligned to the transistor structure. <IMAGE></p> |
