  • Patent number: 8486745
    Abstract: Phase change devices, and particularly multi-terminal phase change devices, include first and second active terminals bridged together by a phase-change material whose conductivity can be modified in accordance with a control signal applied to a control electrode. This structure allows an application in which an electrical connection can be created between the two active terminals, with the control of the connection being effected using a separate terminal or terminals. Accordingly, the resistance of the heater element can be increased independently from the resistance of the path between the two active terminals. This allows the use of smaller heater elements thus requiring less current to create the same amount of Joule heating per unit area. The resistance of the heating element does not impact the total resistance of the phase change device.

    Abstract: Disclosed is semiconductor structure with an insulator layer on a semiconductor substrate and a device layer is on the insulator layer. The substrate is doped with a relatively low dose of a dopant having a given conductivity type such that it has a relatively high resistivity. Additionally, a portion of the semiconductor substrate immediately adjacent to the insulator layer can be doped with a slightly higher dose of the same dopant, a different dopant having the same conductivity type or a combination thereof. Optionally, micro-cavities are created within this same portion so as to balance out any increase in conductivity due to increased doping with a corresponding increase in resistivity. Increasing the dopant concentration at the semiconductor substrate-insulator layer interface raises the threshold voltage (Vt) of any resulting parasitic capacitors and, thereby reduces harmonic behavior. Also disclosed herein are embodiments of a method for forming such a semiconductor structure.

  • Publication number: 20130026468
    Abstract: A graphite substrate is processed to have surface unevenness in a range of 1 ?m to 8 ?m. Thereby, a semiconductor film to be laminated on the graphite substrate has a stable film quality, and thus adhesion of the graphite substrate and the semiconductor layer can be enhanced. When an electron blocking layer is interposed between the graphite substrate and the semiconductor layer, the electron blocking layer is thin and thus the surface unevenness of the graphite substrate is transferred onto the electron blocking layer. Consequently, the electron blocking layer also has surface unevenness approximately in such range. Thus, almost the same effect as a configuration in which the semiconductor layer is directly connected to the graphite substrate can be produced.

  • Publication number: 20120326148
    Abstract: A thin film transistor array panel and a manufacturing method therefor. A shorting bar for connecting a thin film transistor with data lines is formed separate from the data lines, and then the data lines and the shorting bar are connected through a connecting member. As a result, all the data lines are floated during manufacture, so that variation in etching speed between data lines does not occur. Since variation in etching speed between the data lines can be prevented, performance deterioration of the transistor caused by a thickness difference in the lower layer of the data line can be prevented, as can resulting deterioration in display quality. Also, the influence of static electricity can be reduced or eliminated. Furthermore, since the data lines and the shorting bar are connected to each other, the generation of static electricity can be prevented or reduced, and quality testing is more readily performed.
