Patent ID: 7824520

Claim:
A plasma treatment apparatus comprising: a plasma generation unit comprising a first electrode provided on a first substrate and a plurality of second electrodes opposed to the first electrode and provided on a second substrate, wherein the first electrode and the plurality of second electrodes are substantially planar and are disposed in parallel; a gas supply unit adapted to discharge a process gas into a space between the first electrode and the plurality of second electrodes and onto a third substrate to be treated; and a unit for controlling a voltage applied to a selected electrode among the plurality of second electrodes, wherein the plurality of second electrodes are arranged linearly in one line, wherein at least one of the plurality of second electrodes has a length of equal to or less than 1 mm along the one line, on a side of the third substrate to be treated, wherein the first electrode and the plurality of second electrodes are arranged perpendicular to the third substrate to be treated, and wherein the plasma generation unit is configured to move in an X direction and a Y direction.
