  • Publication number: 20050077524
    Abstract: A liquid crystal display (LCD) panel is fabricated with a reduced number of mask processes and includes a thin film transistor (TFT) array substrate and a color filter array substrate. The TFT array substrate includes gate and data lines insulatively crossing each other to define a pixel area, a TFT provided at the crossing of the gate and data lines, a passivation film protecting the TFT, a pixel electrode partially overlapped by the TFT, a gate pad connected to the gate line, and a data pad connected to the data line. The gate line, the gate and data pads, and the pixel electrode include a transparent conductive material. A gate metal material is on the transparent conductive material where the TFT partially overlaps the pixel electrode. The passivation film over the gate and data pads is removed to expose the transparent conductive material included within the gate and data pads.

  • Publication number: 20050077523
    Abstract: A thin film transistor (TFT) substrate is fabricated in three mask processes. In a first mask process, a gate line and a gate electrode are formed. In a second mask process, a data line, a source electrode, a drain electrode, a semiconductor layer, and a first upper storage electrode overlapping the gate line are formed from a gate insulating film, undoped and doped amorphous silicon layers, and a data metal layer. In a third mask process, a pixel hole is formed through protective and gate insulating films within and outside a pixel area, the first upper storage electrode is partially removed, a pixel electrode contacts a side of the drain electrode within the pixel hole at the pixel area, and a second upper storage electrode contacts a side of the first upper storage electrode in the pixel hole outside the pixel area.

  • Publication number: 20050078259
    Abstract: An in plane switching (IPS) mode liquid crystal display (LCD) panel is fabricated with a reduced number of mask processes and includes a thin film transistor (TFT) array substrate with a TFT provided at a crossing of gate and data lines, a protective film protecting the TFT, a pixel electrode connected to the TFT, a common line substantially parallel to the pixel electrode, a common electrode connected to the common line to generate a horizontal electric field with the pixel electrode, and a pad including a transparent conductive material and connected to the gate line, the data line and/or the common line. A color filter array substrate is joined to, and overlaps a portion of, the TFT array substrate. Portions of the protective film where the color filter array substrate which do not overlap the TFT array substrate are removed to expose the transparent conductive material included in the pad.

  • Publication number: 20050029638
    Abstract: Metal leadframes, semiconductor packages made using the leadframes, and methods of making the leadframes and packages are disclosed. In one embodiment, the leadframe includes a rectangular frame. A chip pad and a plurality of leads are within the frame. The lower side of the chip pad and the leads includes one or more vertically recessed horizontal surfaces. The upper side of the chip pad may include a groove around a chip mounting region. In a package, the chip pad supports a semiconductor chip electrically connected to the leads. The lower side of the chip pad and leads are exposed at an exterior surface of the package body. Encapsulant material underfills the recessed lower surfaces of the chip pad and leads, thereby locking them to the encapsulant material. A wire may be reliably bonded to the chip pad within the groove formed in the upper side thereof.
