Abstract
A plasma processing method that is executed by a plasma processing apparatus including a processing container containing a target substrate, a plurality of plasma sources, and a gas supply apparatus for supplying gas includes: supplying the gas from the gas supply apparatus into the processing container; individually controlling intensity of power introduced from each of the plurality of plasma sources into the processing container; and generating plasma of the gas by the intensity of the power introduced from each of the plurality of plasma sources and depositing a desired film on a second surface of the target substrate that is an opposite surface of a first surface of the target substrate so as to apply desired film stress to a film on the first surface.
