  • Method and apparatus for atomic layer etching
    Patent number: 11784029
    Abstract: A method for atomic layer etching may include a step of providing a substrate on which a material to be etched is formed, a modifying step of controlling the substrate at a first temperature and modifying a surface layer of the material to be removed by supplying a modifying gas to the substrate, and an etching step of controlling the substrate at a second temperature different from the first temperature and removing the modified surface layer by supplying an etching gas to the substrate.
    Type: Grant

  • Apparatus of driving lamp and liquid crystal display device using the same
    Patent number: 7221108
    Abstract: An apparatus of driving a lamp includes a first inverter board having a first inverter for supplying a first high-voltage alternating-current waveform via a first high-voltage line to a first electrode of the lamp, and a second inverter board having a second inverter for supplying a second high-voltage alternating-current waveform via a second high-voltage line to a second electrode of the lamp, the second inverter being different from the first inverter.
