  • Publication number: 20230044703
    Abstract: Plasma processing equipment includes a chuck stage for supporting a wafer and including a lower electrode, an upper electrode disposed on the chuck stage, an AC power supply which applies first to third signals having different magnitudes of frequencies to the upper electrode or the lower electrode, a dielectric ring which surrounds the chuck stage, an edge electrode located within the dielectric ring, and a resonance circuit connected to the edge electrode. The resonance circuit includes a filter circuit which allows only the third signal among the first to third signals to pass, and a series resonance circuit connected in series with the filter circuit and having a first coil and a first variable capacitor connected in series and grounded.
