Batch-type remote plasma processing apparatus

1. A plasma processing apparatus, comprising:

a processing chamber in which a plurality of substrates are stacked and accommodated;

a pair of electrodes, each of which is covered with a protecting tube, for isolating from processing gas, and to each of which high frequency electricity is applied;

a guttering-like partition forming a discharging chamber for accommodating the pair of electrodes that is formed at a part of an inner peripheral wall of the processing chamber and that is partitioned from the processing chamber;

a gas supplying means for supplying processing gas into the discharging chamber;

a gas blowout opening provided in the discharging chamber for supplying the processing gas into the discharging chamber; and

a heater surrounding the processing chamber and the discharging chamber for heating the substrates in the processing chamber and the processing gas in the discharging chamber, wherein

the gas blowout opening is opened at a wall portion of the discharging chamber and is opposite an exhaust pipe, and the substrates, while accommodated in the processing chamber, are accommodated at a position outside the discharging chamber and are kept clear of a space between the pair of electrodes.

2. A plasma processing apparatus according to claim 1 , wherein the electrodes are elongated in a direction in which the substrates are stacked.

3. A plasma processing apparatus according to claim 1 , wherein the electrodes are rod-shaped.

4. A plasma processing apparatus according to claim 1 , wherein plasma is generated in the discharging chamber and the processing gas is activated.

5. A plasma processing apparatus according to claim 1 , wherein the gas blowout opening is positioned between the pair of electrodes looking from the substrate side.

6. A plasma processing apparatus according to claim 1 , wherein the gas blows into the substrates in the discharging chamber.
