Patent ID: 8624340

Claim:
A plasma processing apparatus comprising: a case having a chamber that communicates with an opening having a slit shape, and is surrounded by a dielectric member; a gas supply device for supplying a gas to the chamber through a gas introducing port; a conductive unit that is disposed in a manner so as to bridge over the chamber in the case and generates a high-frequency electromagnetic field in the chamber; a high-frequency power supply that supplies high-frequency power to the conductive unit; and a substrate mounting base on which a substrate is mounted, and which is disposed so as to face the opening, wherein a longitudinal direction of the chamber and a longitudinal direction of the opening are disposed in parallel with each other, and the conductive unit is formed by electrically connecting a plurality of conductor members that are disposed in parallel with the longitudinal direction of the chamber, with the chamber being sandwiched therebetween.
