Patent ID: 8028652

Claim:
A plasma processing apparatus, comprising: a process tube in which a plurality of substrates are to be stacked and accommodated, a pair of electrodes extending in the stacking direction of said plurality of substrates, said electrodes being disposed at one side of said plurality of substrates in said process tube, and high frequency electricity being to be applied to said electrodes, protect pipes covering the pair of electrodes, and a gas supply member which is to supply processing gas into a space outside of the protect pipes covering the pair of electrodes, wherein said pair of electrodes are rod-like electrodes extending in a direction in which said plurality of substrates are to be stacked, the rod-like pair of electrodes are bent and pass through a side surface of the process tube, said pair of electrodes do not contact the protect pipes, and a hollow portion of each of the protect pipes is brought into communication with atmospheric pressure outside of the process tube.
