  • Publication number: 20240129167
    Abstract: A communication receiver includes a first signal processing circuit and a second signal processing circuit. The first signal processing circuit includes a first feedforward equalizer and a decision circuit. The first feedforward equalizer processes a received signal to generate a first equalized signal. The decision circuit performs hard decision upon the first equalized signal to generate a first symbol decision signal. The second signal processing circuit includes a second feedforward equalizer, a decision feedforward equalizer, and a first decision feedback equalizer. The second feedforward equalizer processes the first equalized signal to generate a second equalized signal. The decision feedforward equalizer processes the first symbol decision signal to generate a third equalized signal. The first decision feedback equalizer generates a second symbol decision signal according to the second equalized signal and the third equalized signal.

  • Patent number: 7598524
    Abstract: A thin film transistor (TFT) is disclosed, and the thin film transistor comprises: a substrate, a gate electrode, a first adhesion layer, a gate insulting layer, a semiconductor layer, and a source electrode and a drain electrode. The gate electrode is formed on the substrate, and the gate electrode is made of silver. The first adhesion layer is formed between the substrate and the gate electrode. A gate insulating layer is formed on the gate electrode. The semiconductor layer is formed on the gate insulating layer. The source electrode and the drain electrode are formed on parts of the semiconductor layer. Accordingly, the reliable TFT is provided through having the Ag metal with low resistivity and good adhesion characteristics.

  • Patent number: 7403321
    Abstract: An optical microelectromechanical systems (MEMS) device includes a transparent substrate with a plurality of discrete conductive lines, an dielectric layer disposed on the substrate and the conductive lines, reflective members and edge supporters. The reflective members and conductive lines are orthogonal, defining a plurality of pixel areas. Each reflective member is supported by edge supporters arranged around each pixel area and over the dielectric layer by a predetermined gap. The reflective members cover the connecting end of each edge supporter, providing protection from damage during fabrication.

  • Patent number: 7358102
    Abstract: A Method of forming microelectromechanical optical display devices is provided. A sacrificial layer is formed above a substrate. A plurality of posts penetrating the sacrificial layer is formed. A reflective layer and a flexible layer are sequentially formed above the sacrificial layer and the posts. A photoresist layer is formed on part of the flexible layer. By performing wet etching using the photoresist layer as a mask, a portion of the flexible layer is removed to form a patterned flexible layer. The wet etching is stopped on the reflective layer. The photoresist layer is removed. By performing dry etching using the patterned flexible layer as a mask, a portion of the reflective layer is removed to form a patterned reflective layer. A mechanical layer is formed with the patterned flexible and reflective layers. The sacrificial layer is removed to release the mechanical layer.

  • Patent number: 7164524
    Abstract: An optical microelectromechanical (MEMS) device includes a conductive layer, a dielectric layer, a reflective layer and a plurality of supporters between the dielectric layer and reflective layer. The supporters are tapers, or inversed tapers, having an acute angle, wherein a side surface of one of the supporters and the surface of the dielectric layer form the acute angle. Each supporter comprises a horizontal extending portion connecting to the reflective layer, such that the reflective layer is suspended from the dielectric layer by a predetermined gap.
