    摘要: Crystalline semiconductor stripes and an associated fabrication process are provided. The method provides an insulator substrate, and deposits a semiconductor layer overlying the insulator substrate. The semiconductor layer is irradiated using a scanning step-and-repeat laser annealing process, which agglomerates portions of the semiconductor layer. In response to cooling agglomerated semiconductor material, oriented crystalline semiconductor stripes are formed on the insulator substrate. The crystalline semiconductor stripes are aligned approximately with a straight line stripe axis overlying a top surface of the insulating substrate. Each crystalline semiconductor stripe includes a plurality of consecutive ring segments aligned with the stripe axis. The rings segments have a width about equal to the laser annealing process step distance. The crystalline semiconductor stripes typically have a top surface shape of a truncated cylinder or a parabolic cross section.

    摘要: A structure with location-controlled crystallization of an active semiconductor film using a crystal seed has been provided, along with an associated fabrication method. The method forms a first semiconductor film overlying a substrate having a crystallographic orientation. Typically, the structure is polycrystalline or single-crystal. The first semiconductor film is selectively etched, forming a seed region. An insulator is formed with an opening, exposing the seed region. An amorphous second semiconductor film is formed over the insulator layer. The second semiconductor film is laser annealed, partially melting the seed region. Crystal grains are laterally grown in the second semiconductor film having the same crystallographic orientation as the seed region. In TFT fabrication an etching is typically performed to remove the second semiconductor film overlying the seed region, and a transistor active region is formed in the remaining second semiconductor film.

    摘要: A video display is provided with a planar piezoelectric transmitter to transmit ultrasound signals, and a display panel including a plurality of pixels. Each pixel has a data interface to accept a video signal with a variable voltage associated with a range of light intensity values, and to supply a touch signal with a variable voltage derived from a range of reflected ultrasound signal energies. Each pixel is made up of a light device to supply light with an intensity responsive to the video signal voltage, and a storage capacitor to maintain a video signal voltage between refresh cycles. A piezoelectric transducer accepts a reflected ultrasound signal energy and maintains a touch signal voltage between refresh cycles. In one aspect, the storage capacitor and the piezoelectric transducer are the same device. The light device may be a liquid crystal (LC) layer or a light emitting diode.
