摘要:
To provide a production method of a structure with which a degradation of a processing speed is suppressed and plasma processing is performed with using a reliable plasma processing apparatus and which is excellent in repeatability, a plasma processing apparatus, which includes a container whose inside can be exhausted and a gas supply port for supplying a process gas to the container and subjects to plasma processing an object to be processed placed in the container, is characterized in containing a light shielding film that disturbs the incidence of light, which may increase dielectric loss of a permeable window, to this dielectric window on the internal surface of the permeable window permeating high frequency energy for generating the plasma of the above-described gas, and is provided in the above-described container.
