摘要:
The magnetron plasma processing apparatus includes a vacuum chamber in which a semiconductor wafer is accommodated. In the chamber, a pair of electrodes are provided to face each other, and the wafer is placed on one electrode. Between a pair of the electrodes, a vertical electric field is formed, and a horizontal magnetic field is formed by the dipole ring magnet to cross perpendicularly to the electric field. The magnetic field has a gradient of the magnetic field intensity such that the intensity is high on the upstream side and is low on the downstream side in the electron-drift direction. Further, the magnetic field is formed such that the intensity is made uniform over a large area including the end portion of the wafer on the upstream side in the electron-drift direction and a region right outside it.

A plasma processing apparatus includes a process container configured to have a vacuum atmosphere therein. A first upper electrode is disposed to have a ring shape and to face a target substrate placed within the process container. A second upper electrode is disposed radially inside the first upper electrode and electrically insulated therefrom. A first electric feeder is configured to supply a first RF output from a first RF power supply to the first upper electrode at a first power value. A second electric feeder branches from the first electric feeder and is configured to supply the first RF output from the first RF power supply to the second upper electrode at a second power value smaller than the first power value.
摘要:
A plasma processing method is arranged to supply a predetermined process gas into a plasma generation space in which a target substrate is placed, and turn the process gas into plasma. The substrate is subjected to a predetermined plasma process by this plasma. The spatial distribution of density of the plasma and the spatial distribution of density of radicals in the plasma are controlled independently of each other relative to the substrate by a facing portion opposite the substrate to form a predetermined process state over the entire target surface of the substrate.

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.
