Abstract:
A plasma electrode is provided with an electrode plate, a ground plate, and an insulating plate arranged between the electrode plate and the ground plate. Protrusions of the electrode plate are arranged inside through holes of the ground plate and inside through holes of the insulating plate. One of the through hole provided on the center axes of the protrusions and the through hole provided around the through hole discharges a first processing gas to below the ground plate. The other of the through holes exhausts a gas existing below the ground plate. A second flow path around the protrusions supplies a second processing gas supplied via a first flow path to a gap between outer walls of the protrusions and inner walls of the through holes. The second processing gas supplied to the gap is converted into plasma by high frequency power applied to the electrode plate.

Claim (Index 11):
A plasma processing device, comprising:\n a chamber; a mounting table disposed in the chamber and configured to hold a substrate to be processed; and a plasma electrode provided above the chamber so as to face the mounting table, wherein the plasma electrode includes a first electrode plate having a plurality of cylindrical protrusions and to which high frequency power is applied, a ground plate provided with a plurality of cylindrical first through holes having an inner diameter larger than an outer diameter of the protrusions, and an insulating plate provided with a plurality of cylindrical second through holes having an inner diameter larger than the outer diameter of the protrusions and disposed between the first electrode plate and the ground plate, the first electrode plate, the insulating plate, and the ground plate are overlappingly arranged so that the protrusions are arranged inside the first through holes and the second through holes, a third through hole is provided in each of the protrusions along a center axis of each of the protrusions, a first flow path is provided between the first electrode plate and the insulating plate, a second flow path communicating with the first flow path is provided around the protrusions, a fourth through hole is provided in the ground plate around each of the first through holes, one of the third through hole and the fourth through hole discharges a first processing gas to below the ground plate, the other of the third through hole and the fourth through hole exhausts a gas existing below the ground plate, the second flow path communicates with a gap formed between outer walls of the protrusions and inner walls of the first through holes, and supplies a second processing gas supplied via the first flow path to the gap, and the second processing gas supplied to the gap is converted into plasma in the gap by the high frequency power applied to the first electrode plate.
