PLASMA PROCESSING APPARATUS

In a plasma processing apparatus that can adjust an induction magnetic field distribution of power feeding sections of an induction coil, correct a plasma distribution on a specimen, and apply uniform plasma processing to the specimen, the specimen is subjected to plasma processing, a dielectric window that forms the upper surface of the vacuum processing chamber, a gas lead-in section that leads gas into the vacuum processing chamber, a specimen table that is arranged in the vacuum processing chamber and on which the specimen is placed, an induction coil provided above the dielectric window, and a radio-frequency power supply that supplies radio-frequency power to the induction coil. The plasma processing apparatus includes a flat conductor arranged below the induction coil. The induction coil includes crossing power feeding sections. The conductor is arranged below the power feeding sections.
