Patent ID: 7927455

Claim:
A plasma processing apparatus comprising: a sealable chamber that is sealable; a gas supply section that supplies a reactive material gas into the chamber; and a plurality of cathode and anode electrode pairs provided within the chamber, the electrode pairs being connected to an external power supply and configured to produce plasma discharges through the material gas, respectively, wherein the plurality of cathode and anode electrode pairs are provided at a distance from one another at which the plasma discharges are prevented from interfering with one another, and have an empty space between the adjacent cathode and anode electrode pairs; a processing target is disposed between a cathode electrode and an anode electrode in each cathode and anode electrode pair, and subjected to a plasma discharge processing; a distance between the cathode electrode and the anode electrode in the each anode and cathode electrode pair is a predetermined distance, and a distance between a cathode electrode of one of the anode and cathode electrode pairs and an anode electrode of an anode and cathode electrode pair adjacent to the one of the anode and cathode electrode pairs is at least twice as large as the predetermined distance.
