    摘要: A focus ring and a plasma processing apparatus capable of improving an in-surface uniformity of a surface and reducing occurrences of deposition on a backside surface of a peripheral portion of a semiconductor wafer compared to a conventional case are provided. Installed in a vacuum chamber is a susceptor for mounting the semiconductor wafer thereon and a focus ring is installed to surround the semiconductor wafer mounted on the susceptor. The focus ring includes an annular lower member made of a dielectric, and an annular upper member made of a conductive material and mounted on the lower member. The upper member includes a flat portion which is an outer peripheral portion having a top surface positioned higher than a surface to be processed of the semiconductor wafer W, and an inclined portion which is an inner peripheral portion inclined inwardly.

    摘要: A plasma processing apparatus enabling reduction of the deposition of CF polymers in a processing chamber. The plasma processing apparatus (1) comprises a plasma processing vessel (3) having a large diameter at the lower portion and a small diameter at the upper portion to define a processing chamber (2) inside the vessel. The pressure in the processing chamber (2) is reduced to a predetermined vacuum atmosphere, and a processing gas containing a CF gas is introduced into the processing chamber (2) and changed to a plasma, and thereby a semiconductor wafer (34) is subjected to a desired microprocessing. A Y2O3 sprayed coating (41) is formed over a predetermined area of an inner wall (3b) of the plasma processing vessel (3) so that solid particles of CF polymers produced from the decomposition components of the CF gas by the plasma may be prevented from flying and adhering to the inner wall (3b) and the surface of the parts in the processing chamber, and the CF polymers may be prevented from depositing.
