  • Publication number: 20080001232
    Abstract: A method for manufacturing a substrate of a liquid crystal display device is disclosed. The method includes forming a conductive line structure with low resistance to improve the difficulty of the resistance matching. The method can effectively reduce the resistance of the conductive line of the LCD panel to increase the transmission rate of the driving signal. Hence, the increasing yield of products can reduce the cost of manufacturing, and can meet the requirement of the large-size and high-definition thin film transistor liquid crystal display device.

  • Publication number: 20070178714
    Abstract: A method, system and scan lens for use therein are provided for high-speed, laser-based, precise laser trimming at least one electrical element along a trim path. The method includes generating a pulsed laser output with a laser, the output having one or more laser pulses at a repetition rate. A fast rise/fall time, pulse-shaped q-switched laser or an ultra-fast laser may be used. Beam shaping optics may be used to generate a flat-top beam profile. Each laser pulse has a pulse energy, a laser wavelength within a range of laser wavelengths, and a pulse duration. The wavelength is short enough to produce desired short-wavelength benefits of small spot size, tight tolerance, high absorption and reduced or eliminated heat-affected zone (HAZ) along the trim path, but not so short so as to cause microcracking. In this way, resistance drift after the trimming process is reduced.

  • Publication number: 20070153147
    Abstract: A method for manufacturing a pixel structure is provided. A first conductive layer is formed on a substrate and patterned using a first mask to form a gate. A dielectric layer is formed over the substrate to cover the gate. A semiconductor material layer and a second conductive layer are sequentially formed over the dielectric layer. The second conductive layer is patterned using a second mask to form a pixel electrode. A patterned photo-resist layer is formed by using the first mask again such that the semiconductor material layer above the gate is protected. The semiconductor material layer is patterned to form a semiconductor layer using the pixel electrode and the patterned photo-resist layer as an etching mask. The patterned photo-resist layer is removed. A third conductive layer is formed and patterned to form a source/drain by using a third mask. The drain is electrically connected to the pixel electrode.

  • Publication number: 20070096763
    Abstract: A laser processing system implements a method for aligning a probe element (e.g., a probe pin) with a device interface element (e.g., a contact pad of a circuit substrate). First, the laser processing system generates an optical reference beam at one or more predetermined positions to calibrate a reference field. The laser processing system then detects a position of the probe element in the reference field. The laser processing system also determines a relative position of the device interface element in the reference field. Based on the position of the probe element and the device interface element, the laser processing system then initiates alignment of the probe element and the device interface element. In one application, alignment of the probe element and the device interface element further includes contacting the probe element to the device interface element to make an electrical connection.

  • Publication number: 20060199375
    Abstract: A structure applied to a photolithographic process is provided. The structure includes at least a film layer, an optical isolation layer, an anti-reflection coating and a photoresist layer sequentially formed over a substrate. In the photolithographic process, the optical isolation layer stops light from penetrating down to the film layer. Since the optical isolation layer is set up underneath the photoresist layer, light emitted from a light source during photo-exposure is prevented from reflecting from the substrate surface after passing through the film layer. Thus, the critical dimensions of the photolithographic process are unaffected by any change in the thickness of the film layer.

  • Publication number: 20060160332
    Abstract: A method, system and scan lens system are provided for high-speed, laser-based, precise laser trimming at least one electrical element. The method includes generating a pulsed laser output having one or more laser pulses at a repetition rate. Each laser pulse has a pulse energy, a laser wavelength within a range of laser wavelengths, and a pulse duration. The method further includes selectively irradiating the at least one electrical element with the one or more laser pulses focused into at least one spot having a non-uniform intensity profile along a direction and a spot diameter as small as about 6 microns to about 15 microns so as to cause the one or more laser pulses to selectively remove material from the at least one element and laser trim the at least one element while avoiding substantial microcracking within the at least one element.
