Document Type and Number:
Japanese Patent JP2023112675
Kind Code:
A
Abstract:
To provide a substrate support and a plasma processing apparatus enabling improvement of efficiency of a low frequency side of bias electric power.SOLUTION: A substrate support is arranged in a processing container, and includes: an electrostatic chuck that is formed of dielectric material and has a first support surface for supporting a substrate, and includes, inside the electrostatic chuck, a first electrode and a second electrode in order from the first support surface side; and a base supporting the electrostatic chuck. The second electrode is arranged at a position where distance from the second electrode to the first support surface is equal to or less than distance from the second electrode to the base. A voltage for attracting the substrate is applied to the first electrode, and bias electric power is supplied to the second electrode.SELECTED DRAWING: Figure 1
