  • Patent number: 7511327
    Abstract: The present invention relates to a structure of a capacitor, in particular using niobium pentoxide, of a semiconductor capacitor memory device. Since niobium pentoxide has a low crystallization temperature of 600° C. or less, niobium pentoxide can suppress the oxidation of a bottom electrode and a barrier metal by heat treatment. However, according to heat treatment at low temperature, carbon incorporated from CVD sources into the film is not easily oxidized or removed. Therefore, a problem that leakage current increases arises. As an insulator film of a capacitor, a layered film composed of niobium pentoxide film and a tantalum pentoxide film, or a layered film composed of niobium pentoxide films is used. By the use of the niobium pentoxide film, the dielectric constant of the capacitor can be made high and the crystallization temperature can be made low. By multiple-stage formation of the dielectric film, leakage current can be decreased.

Multiple npn junctions are formed apart from each other in concentric circular patterns. With this configuration, steep breakdown characteristics can be obtained, which results in good constant-voltage diode characteristics. Being formed in a manufacturing process of a MOS transistor, the present protection diode contributes to process streamlining and cost reduction. By selecting the number of npn junctions according to breakdown voltage, control of the breakdown voltage can be facilitated.

  • Patent number: 7432564
    Abstract: A method for fabricating a pixel structure is provided. First, a gate, a scan line, and a first terminal are formed on a substrate. A gate insulating layer is formed over the substrate to cover the gate, the scan line, and the first terminal. After defining the semiconductor layer, the gate insulating layer is patterned to exposure the first terminal. A transparent conductive layer is formed over the substrate and a patterned photoresist layer is formed on the transparent conductive layer. The transparent conductive layer is patterned using the patterned photoresist layer as a mask, so as to define a source, a drain, a data line, a pixel electrode, a second terminal, and a contact pad. Because only four photomasks are used to implement the above method for fabricating the pixel structure, the cost of manufacturing can be reduced.
