Abstract:
1. A plasma processing apparatus, comprising: a process tube including an electrode chamber and a processing chamber, a plurality of substrates being stacked and accommodated in said processing chamber; a rod-like pair of electrodes that is disposed in said electrode chamber, said electrodes being covered by cylindrical protecting members and extending in a stacking direction of said plurality of substrates, said electrode chamber being separated from said processing chamber by a partition disposed around said pair of electrodes, and high frequency electric power being applied to said electrodes; and a gas supply member for supplying processing gas vertically stood between said pair of electrodes and stood on a position in a vicinity of an inner peripheral surface of said process tube at a position on an opposite side from an exhaust pipe, wherein said pair of electrodes are used when plasma is generated when said substrates are processed, the processing gas for processing said substrates is supplied into said electrode chamber, the processing gas is activated by the plasma generated by said pair of electrodes in said electrode chamber, and the activated processing gas is supplied to said substrates to process said substrates, and the pair of electrodes are bent and pass through a side surface of the process tube, wherein said partition extends in a circumferential direction of said process tube such that said partition does not encompass said substrates in the circumferential direction and said partition is elongated in said stacking direction of said substrates.
