    Abstract: A plasma processing apparatus includes a chamber, a substrate support, a radio-frequency power supply, and a bias power supply system. The substrate support is in the chamber and includes a central portion on which a substrate is placeable. The radio-frequency power supply generates source radio-frequency power. The bias power supply system respectively provides first electrical bias energy and second electrical bias energy to a first electrode and a second electrode. The first electrode is at least in the central portion of the substrate support. The second electrode is in an outer portion located outward from the central portion in a radial direction that is radial from a center of the central portion. The bias power supply system adjusts the first and second electrical bias energy to increase electric field strength above one of the central portion or the outer portion earlier than electric field strength above the other portion.
