Abstract: A plasma processing apparatus includes a worktable in a process chamber to horizontally place a target substrate thereon. A plasma generation space is defined above and around the worktable within the process chamber. The plasma generation space includes a peripheral plasma region and a main plasma region respectively located outside and inside an outer edge of the target substrate placed on the worktable. The apparatus further includes a magnetic field forming mechanism configured to form a magnetic field within the peripheral plasma region. The magnetic field includes magnetic force lines extending through the peripheral plasma region between a start position and an end position, at least one of which is located radially inside a sidewall of the process chamber.

Abstract: A plasma processing apparatus for converting a processing gas into a plasma by a high frequency power in a processing chamber and performing a plasma processing on a substrate mounted on a mounting table includes a ring portion disposed to surround the substrate on the mounting table, and a temperature control unit for establishing a temperature difference between the ring portion and the substrate, such that the ring portion is at least 50° C. higher than the substrate. Further, the processing gas generates chlorine radicals, and the temperature control unit is at least one of a heating unit for heating the ring portion and a cooling unit for cooling the mounting table.

Abstract: [Object] It is an object of the present invention to readily replace a plasma control member disposed to surround a substrate to control plasma in case of plasmarizing a processing gas in the processing vessel by using a high frequency power and performing a substrate on a susceptor by using the plasma. [Constitution of the Invention] A plasma control sheet whose, e.g., rear surface is coated with an adhesive is detachably attached to a ring member provided to surround a substrate mounted on a susceptor. In this case, attachment/detachment of the sheet is carried out with ease so that the burden of an operator is decreased and an operation rate of the apparatus is increased.
