    Abstract: A plasma substrate processing apparatus according to one embodiment of the present invention comprises: a process chamber; an upper electrode disposed in the process chamber; a substrate holder disposed under the upper electrode and facing the upper electrode to support a substrate; and an RF power source for applying RF power to the substrate holder. The upper electrode includes: an upper electrode conductive plate having lower surfaces with different heights from the substrate holder according to positions thereof; and a compensating plate coupled to a lower portion of the conductive plate, having a different thickness according to positions thereof to compensate for a height difference according to the positions of the upper electrode conductive plate, and having a dielectric constant. The lower surface of the compensating plate is coplanar.
