Abstract
A plasma processing apparatus includes a cylindrical processing chamber with a sidewall having an opening, to accommodate substrates on respective stages. The plasma processing apparatus includes a plasma compartment wall with an outer surface, the plasma compartment wall being hermetically provided at the sidewall of the processing chamber to close the opening of the sidewall of the processing chamber, and the plasma compartment wall defining a plasma formation space. The plasma processing apparatus includes a first plasma electrode pair consisting of first electrodes, the first electrodes being arranged opposite each other, on opposite sides of the outer surface of the plasma compartment wall. The plasma processing apparatus includes a second plasma electrode pair consisting of second electrodes, the second electrodes being arranged opposite each other, on the opposite sides of the outer surface of the plasma compartment wall.
