A plasma processing apparatus includes a wafer support fixture in the chamber and configured to support a wafer, an upper electrode in the chamber and spaced apart from the wafter support fixture, a magnet assembly configured to apply a magnetic field into a chamber, the magnet assembly including a plurality of first magnets and a plurality of second magnets arranged in an annular shape, and a horizontal distance from a central axis of the chamber to each of the plurality of first magnets and each of the plurality of second magnets is less than a radius of the wafer.

Plasma processing apparatus

An apparatus for measuring parameters of plasma includes a cutoff probe. The cutoff probe includes: a first antenna having a line shape and configured to emit a microwave to the plasma in response to the signal provided by at least one processor; a second antenna having a line shape and configured to generate an electrical signal in response to receiving the microwave emitted by the first antenna and transferred through the plasma; a first insulating layer; a second insulating layer; a first shield; a second shield; an end protection layer covering an end of each of the first insulating layer, the second insulating layer, the first shield, and the second shield; a first antenna protection layer, of insulating nature, covering the first antenna; and a second antenna protection layer, of insulating nature, covering the second antenna.
