    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: In an oxide film etching process, a plasma having a suitable ratio of CF3, CF2, CF, and F is necessary, and there is a problem in that the etching characteristic fluctuates in accordance with a temperature fluctuation of the etching chamber. Using a UHF type ECR plasma etching apparatus having a low electron temperature, a suitable dissociation can be obtained, and by maintaining the temperature of a side wall of the etching chamber in a range from 10° C. and 120° C., a stable etching characteristic can be obtained. Since oxide film etching using a low electron temperature and a high density plasma can be obtained, an etching result having a superior characteristic can be obtained, and, also, since the side wall temperature adjustment range is low, a simplified apparatus structure and a heat resistant performance countermeasure can be obtained easily.

    摘要: The present invention relates to a heat treatment apparatus that performs activation annealing or defect repair annealing and surface oxidization which succeed impurity doping intended to control the conductive property of a semiconductor substrate. In the present invention, a sample to be heated is placed on a lower electrode in a plasma treatment chamber. A gap between an upper electrode and the lower electrode is filled with a gap whose main raw material is a rare gas (helium, argon, krypton, xenon, or the like) having a pressure close to the atmospheric pressure. A power fed from a high-frequency power supply is applied to the upper electrode in order to induce an atmospheric-pressure glow discharge. Gas heating in the gap between the electrodes, which depends on the glow discharge, is used to heat-treat the sample to be heated.
