A review is presented of experimental devices with permanent magnets for electron cyclotron resonance to produce large-diameter uniform plasmas. The devices are classified into 7 groups depending on device symmetry, magnet arrangement, plasma-drift direction and microwave coupling. Their characteristic points are clarified and the most optimal device construction and arrangement are discussed from a viewpoint of producing uniform plasmas necessary for large-scale plasma processing.
