Abstract
A plasma processing apparatus includes: a plasma chamber including a first area and a second area; a first radio frequency (RF) power source transmitting pieces of first RF power to the first area; a second RF power source transmitting second RF power to the second area; a controller configured to control the first RF power source and the second RF power source; and a first coil and a second coil arranged in the second area, wherein the controller spatially controls plasma in the first and second areas by controlling a signal of a current applied to the first coil and a signal of a current applied to the second coil, and temporally controls the plasma in the first and second areas by controlling a signal of the first RF power transmitted from the first RF power source and a signal of the second RF power transmitted from the second RF power source.
