  • Patent number: 6884669
    Abstract: Alternate methods of forming low resistance “hatted” polysilicon gate elements are provided that increase the effective area in the polysilicon gate for silicide grain growth during silicide formation. The expanded top portion helps to prevent silicide agglomeration in the silicide regions, thereby maintaining or reducing electrode resistance, improving high-frequency performance, and reducing gate delay in sub micron FET ULSI devices, without increasing the underlying active channel length.

  • Publication number: 20040248391
    Abstract: The invention relates to a lifting and supporting device for handling and positioning particularly large-surface elements in the shape of panels, especially in plasma processing installations. Said lifting and supporting device comprises a particularly metallic base plate, on which a plurality of particularly dielectric pins are arranged. Said pins may be set in pin holes especially provided in the base plate. Said panel-shaped element may be positioned on the pin end for the handling thereof or during a plasma processing. Said panel-shaped element may present an electrostatic charge. A small diameter for the pins and pin holes is selected such that, in conformity with the panel-shaped element provided with the electrostatic charge, an undesired electrostatic charge on said panel-shaped element is essentially avoided or, in conformity with the panel-shaped element to be plasma processed, a plasma perturbation in the area of the pin holes or pins is essentially avoided.

  • Patent number: 6825105
    Abstract: In the manufacture of trench-gate power MOSFETs, trenched Schottky rectifiers and other devices including a Schottky barrier, a guard region (15s), trenched insulated electrode (11s) and the Schottky barrier (80) are self-aligned with respect to each other by providing spacers (52) to form a narrow window (52a) at a wider window (51a) in a mask pattern (51, 51s) that masks where the Schottky barrier (80) is to be formed. The trenched insulated electrode (11s) is formed by etching a trench (20) at the narrow window (52a) and by providing insulating material (17) and then electrode material (11s) in the trench. The guard region (15s) is provided by introducing dopant (61) via the wider window (51a). The mask pattern (51, 51s) masks the underlying body portion against this dopant introduction and is sufficiently wide (y8) to prevent the dopant (61) from extending laterally into the area where the Schottky barrier (80) is to be formed.

  • Patent number: 6815347
    Abstract: The present invention provides a method of forming a TFT and a reflective electrode having recesses or projections with reduced manufacturing cost and a reduced number of manufacturing steps, and provides a liquid crystal display device to which the method is applied. A photosensitive film 8 is formed on a metal film 7. Then, remaining portions 81, 82 and 83 are formed from the photosensitive film 8. Then, the metal film 7 is etched by using the remaining portions 81, 82 and 83 as masks. And then, a photosensitive film 9 and a reflective electrode film 10 are formed without removing the remaining portions 81, 82 and 83.

  • Patent number: 6790753
    Abstract: A Schottky diode is fabricated by a sequence of fabrication by a sequence of fabrication steps. An active region of a semiconductor substrate is defined in which a Schottky diode is fabricated. At least first and second layers of insulating material are applied over the active area. A first layer of insulating material, having a first etching rate, is applied over the active area. A second layer of insulating material having a second, greater, etch rate is applied over the first layer of insulating material to a thickness that is about twice the thickness of the first layer of insulating material. The insulating material is patterned and a window is etched through the layers of insulating material to the semiconductor substrate. Metal is applied and unwanted metal is etched away leaving metal in the window forming a Schottky contact therein. One or more barrier layers may be employed.

  • Patent number: 6737305
    Abstract: A Thin Film Transistor (TFT) manufacture method, comprising manufacture of a gate, a gate isolation layer, a channel layer, and a source/drain. Wherein, the manufacture of the channel layer comprises: forming a first a-Si layer by using a low deposition rate (LDR) (Chemical Vapor Deposition, CVD); forming a second a-Si layer by using a high deposition rate (HDR); and forming an N+Mixed a-Si layer. When the first a-Si layer is formed in the present invention, the flux ratio of H2/SiH4 is adjusted to a range from 0.40 to 1.00 to increase the number of defects in the first a-Si layer. When the TFT is irradiated by the light, the photo leakage current generated in the channel layer is trapped in the defects in the first a-Si layer. Therefore, the TFT photo leakage current can be significantly reduced.
