ABSTRACT:
A plasma processing apparatus includes a radio frequency generator, a plasma processing chamber, a matching circuit for impedance matching between the radio frequency generator and the plasma processing chamber, and matching circuit adjusting means for matching the output impedance of the matching circuit to the impedance of the plasma processing chamber in a nondischarge state. The matching circuit is a product matching circuit that is produced based on a circuit constant of an adjusting matching circuit. The adjusting matching circuit is disposed between the radio frequency generator and the plasma processing chamber for a required plasma treatment and the circuit constant is determined by impedance matching between the radio frequency generator and the plasma processing chamber so that the adjusting matching circuit matches the load impedance of the plasma processing chamber.
