Abstract:
Disclosed is a metal contact structure and method for a thin film transistor array in liquid crystal display in order to prevent source/drain electrode metal layer from plasma damage and oxide insulator formation thereon during contact hole process, such that low contact resistance is obtained between the source/drain electrode metal layer and top-ITO conductive layer, wherein a thin film transistor structure is formed on a substrate and a metal oxide conductive film is covered on the source/drain electrode metal layer of the thin film transistor structure before an insulative passivation layer is deposited over the thin film transistor structure. During the passivation layer is etched to form contact hole for the source/drain electrode metal layer to contact with the top-ITO conductive layer thereafter formed, the metal oxide conductive film prevents the underlying source/drain electrode metal layer from plasma damage and oxide insulator formation thereon, thereby obtaining good contact between the source/drain electrode metal layer and the top-ITO conductive layer.
Abstract:
The method of manufacturing an optical interference color display is described. A first electrode structure is formed over a substrate first. At least one first area, second area and third area are defined on the first electrode structure. A first sacrificial layer is formed over the first electrode structure of the first area, the second area and the third area. Moreover, a second sacrificial layer is formed over the first sacrificial layer inside the second area and the third area. In addition, a third sacrificial layer is formed over the second sacrificial layer inside the third area. The etching rates of all sacrificial layers are different. Then, a patterned support layer is formed over the first electrode structure. Next, a second electrode layer is formed and the sacrificial layers are removed to form air gaps. Therefore, the air gaps are effectively controlled by using the material having different etching rates.
Abstract:
A first electrode and a sacrificial layer are sequentially formed on a substrate, and then first openings for forming supports inside are formed in the first electrode and the sacrificial layer. The supports are formed in the first openings, and then a second electrode is formed on the sacrificial layer and the supports, thus forming a micro electro mechanical system structure. Afterward, an adhesive is used to adhere and fix a protection structure to the substrate for forming a chamber to enclose the micro electro mechanical system structure, and at least one second opening is preserved on sidewalls of the chamber. A release etch process is subsequently employed to remove the sacrificial layer through the second opening in order to form cavities in an optical interference reflection structure. Finally, the second opening is closed to seal the optical interference reflection structure between the substrate and the protection structure.
