    摘要: A plasma processing apparatus in which power consumption is reduced, which can generate uniform plasma in a large range and in which minute processing in high etching selectivity and in high aspect ratio is enabled is disclosed. High density plasma is generated in a vacuum vessel housing a processed sample utilizing an electron cyclotron resonance phenomenon caused by an electromagnetic wave in an ultra-high frequency band and a magnetic field and the surface of the processed sample is etched using this plasma. An electromagnetic wave in an ultra-high frequency band for generating plasma is radiated from a planar conductive plate consisting of graphite or silicon which is arranged opposite to the surface of the processed sample into space inside the vacuum vessel. High density plasma in the low degree of dissociation can be generated by using an electromagnetic wave in an ultra-high frequency band and as a result, the controllability of etching reaction can be enhanced. Further, a radical effective in etching can be increased by reaction between the surface of a planar conductive plate for radiating an electromagnetic wave and plasma.

    摘要: A capacity control device controls an amount of fluid bypassed from a compression chamber formed between contacts of a stationary and revolving spiral elements into a suction chamber by an actuator. The capacity control device provides a feedback mechanism in which a relation between a suction pressure of the compressor and a pressure of actuating the actuator is a function of the first degree and controls the suction pressure to be constant. A capacity control amount of the compressor can be determined only by the suction pressure of the compressor independent of other variation factors. Accordingly, the minimum suction pressure can be restricted strictly and frost control can be attained by the compressor itself.

    摘要: In a plasma processing method for conducting etching on an object to be processed by generating plasma from depositional gas introduced into a processing chamber and exposing the object to be processed to the plasma in a state in which radio frequency power is applied, the object to be processed is etched under etching conditions that a deposit film on an inner wall of the processing chamber becomes amorphous by repeating a first period during which the object to be processed is exposed to plasma and a second period during which the object to be processed is exposed to plasma and an etching rate is lower as compared with the first period. Consequently, particles due to increase in the number of processed sheets of the object to be processed can be suppressed.
