  • Patent number: 9773645
    Abstract: A remote plasma generator includes a body, a driver, and a protection tube. The body includes a gas injection port, a plasma exhaust port, and a plasma generation pipe through which discharge gas or plasma flow. The driver is coupled to the body and generates a magnetic field and plasma in the body. The protection tube is at an inner side of the plasma generation pipe to protect the plasma generation pipe from plasma.

  • Publication number: 20090255555
    Abstract: A method and apparatus for cleaning a workpiece are disclosed. A gas and cleaning solution are supplied to an atomizing nozzle which atomizes the cleaning solution and sprays the top surface of a workpiece with an atomized spray. A liquid having a controlled gas content is flowed to the top surface of the workpiece from a rinse nozzle. Megasonic energy is applied from the backside of the workpiece.

  • Patent number: 7352129
    Abstract: A plasma display panel having higher light-emitting luminance and efficiency of a discharge cell includes: plurality of first barriers successively formed on a substrate at predetermined intervals; a plurality of first sustain electrodes formed at a width more than 40% of a pixel pitch, which is an overall distance of four of the barriers, to be orthogonal to the first barriers; a plurality of second sustain electrodes spaced apart from the first sustain electrodes at a distance less than 20% of the pixel pitch and mated with the first sustain electrodes one by one; a dielectric layer formed at a thickness of 25 ?m or more to cover the first and second sustain electrodes; and a plurality of pads formed on some of the dielectric layer corresponding to the first sustain electrodes and the second sustain electrodes in each discharge cell.
