  • Patent number: 7098985
    Abstract: The invention provides highly reliable wiring and connection terminals of an electro-optic device used as a transfiective liquid crystal device or the like. Since sidewalls and a part of an upper surface of a data line are covered with a reflection film, a central layer is not etched by an etchant when the reflection film is formed by patterning. In addition, since a transparent conductive film is connected to an upper layer of the data line via a contact hole, the resistance of a connection terminal can be decreased, and superior conduction can be obtained.

  • Publication number: 20060070071
    Abstract: An instruction file execution device which includes a receiver, a comparison section and a job execution section. The receiver receives an instruction file and a usable money amount, which instruction file describes a job flow which defines linking of a number of jobs. The comparison section compares an execution charge of a job being handled of the jobs of the instruction file received by the receiver with the usable money amount received by the receiver. If the comparison section determines that the usable money amount is greater than or equal to the execution charge, the job execution section executes the job being handled.

    Abstract: In a process for producing a thin-film device, a conducting layer composed of an anodically oxidizable metal is formed on a substrate and is etched to form gate bus lines and gate electrode having upper surfaces parallel to the substrate and inclined side surfaces. The gate bus lines and the gate electrodes are anodically oxidized, so that they include inner conducting portions and outer insulating oxide films covering the inner conducting portions. The outer insulating films prevent the bus lines from short circuiting, and the inclined side surfaces of the bus lines makes it possible to fabricate a dense wiring arrangement.

  • Patent number: 6534789
    Abstract: Semiconductor islands are formed on an insulating substrate. A gate insulating layer is formed to traverse an intermediate region of each island, and a gate electrode with tapered sidewalls is formed thereon to leave wing-shaped gate insulating layer exposed at both sides. Ion implantation is done to form heavily doped regions in the semiconductor islands outside the gate insulating layers, and lightly doped drain regions under the wing regions of the gate insulating layer. An interlayer insulating layer is formed thereon to cover the gate electrodes, gate insulating layers, and the semiconductor islands. However, if the gate electrode layer and gate insulating film are patterned in the same shape, a step becomes high.
