  • Patent number: 7648120
    Abstract: An iris arrangement has first and second annular carrier elements annular elements coaxially arranged and circumferentially interlocked with one another so as to be independently rotatable. A plurality of iris elements each have a first compliant beam element coupled at a first end thereof to the iris element and at a second end thereof to the first annular carrier element, and a second compliant beam element coupled at a first end thereof to the associated iris element and at a second end thereof to the second annular carrier element. Rotatory motion of the carrier elements relative to each other results in substantially radial displacement of each of the iris elements. The plurality of iris elements communicate with one another when disposed in a radially innermost position. A web covers a region between the plurality of iris elements and the circumference of the first and second annular elements.

  • Publication number: 20090185126
    Abstract: Provided are a metal line, a method of forming the same, and a display using the same. To increase resistance of a metal line having a multilayered structure of CuO/Cu and prevent blister formation, a plasma treatment is performed using a nitrogen-containing gas and a silicon-containing gas or using a hydrogen or argon as and the silicon-containing gas. Accordingly, a plasma treatment layer such as a SiNx or Si layer is thinly formed on the copper layer, thereby preventing an increase in resistance of the copper layer and also preventing blister formation caused by the damage of a copper oxide layer. Consequently, it is possible to improve the reliability of a copper line and thus enhance the reliability of a device.

The semiconductor pattern includes an active layer being overlapped with the gate electrode and a low band gap portion having a lower energy band gap than the active layer. The source and drain electrodes are spaced apart from each other to be overlapped with the semiconductor pattern. Therefore, the semiconductor pattern includes a low band gap portion having a lower energy band gap than the active layer, so that electron mobility may be increased in a channel formed along the low band gap portion so that electric characteristics of the TFT may be enhanced.
