Patent ID: 8875656

Claim:
A substrate processing apparatus comprising: a processing chamber in which a substrate is mounted; a gas supply unit that supplies processing gas into the processing chamber; a gas exhaust unit that exhausts atmospheric gas in the processing chamber; at least a pair of electrodes to which high-frequency power is applied to set the processing gas to an active state; and a mount pipe in which each of the pair of electrodes is mounted while at least one place thereof is bent, wherein each of the electrodes comprises a core wire formed of a metal and plural pipe bodies that are joined consecutively to one another through the core wire so as to be bendable, less thermally deformed than the core wire, and are formed of an insulating material, wherein: each of the electrodes is further provided with a flexible meshed member that is formed of a metal and provided so as to cover the outer surfaces of the plural pipe bodies, a first end side of a first electrode of the at least pair of electrodes is configured to be inserted into the mount pipe and a second end side of the first electrode is configured to be pressed, which allows the first electrode to be inserted in the mount pipe along a bent portion of the mount pipe, and the plural pipe bodies adjoining each other come into contact with at least a portion of an adjoining pipe body.
