  • Publication number: 20170314133
    Abstract: A plasma reactor for generating a plasma for use in depositing a thin film on a large area wafer, such as in the manufacturing of solar cells. A plasma electrode unit in the plasma reactor is divided into a plurality of discrete electrodes, and RF electric power is sequentially applied to the divided plasma electrodes in accordance with a phase angle detected by a phase control unit. The sequential application of high frequency RF power across the divided plasma electrode unit resolves a standing wave problem in the plasma applied over a large area corresponding to a large area wafer.

  • Publication number: 20170221683
    Abstract: A cleaning apparatus of an exhaust path of a process reaction chamber used in a manufacturing of articles including a semiconductor or an LCD. The cleaning apparatus of the exhaust path includes a housing having an inflow pipe, connected to an upstream end of the exhaust path, an outflow pipe, connected to a downstream end of the exhaust path, and a connecting pipe disposed between the inflow pipe and the outflow pipe. A radio frequency generator in the housing applies radio frequency power to the inflow pipe and to the outflow pipe via respective coils. Plasma induced within the inflow and outflow pipes from RF power applied via the respective coils causes the generation of radicals from the exhaust gas flowing within. The radicals act to dislodge accumulated particulates within the exhaust path downstream of the cleaning apparatus.

  • Patent number: 7915616
    Abstract: A display device includes a first pixel and a second pixel. The first pixel and the second pixel are defined by a first gate bus line, a second gate bus line, a first power supply line and a second power supply line. A data bus line between the first supply line and the second supply line divides the first pixel from the second pixel line. Accordingly, the pixel shares a data bus line or a power supply line with adjacent pixel. Advantageously, thereby, more space between lines prevents defects caused during fabricating the display device and improve a reliability of the display device.
