Abstract:
1. A plasma processing apparatus, characterized in that, including: a reaction chamber, a first electrode plate and a second electrode plate which are arranged opposite to each other in the reaction chamber, the first electrode plate being located in the top of the reaction chamber, the second electrode plate being located in a lower part of the reaction chamber for supporting a substrate to be processed, and the plasma processing apparatus further includes, a matching device, a power distribution device and a power supply device; the first electrode plate includes at least two sub-electrode plates insulated from each other; the power supply device is connected to the power distribution device through the matching device; the power distribution device is connected to the first electrode plate, for inputting and distributing the power of the power supply device to each of the sub-electrode plates to obtain an individual electric field between each sub-electrode plate and the second electrode plate so as to control the density and the intensity of plasma generated under each sub-electrode plate; and the power distribution device includes at least one of a capacitor and an inductor.
