    摘要: A plasma processing apparatus comprises a plasma chamber having a gas inlet opening and a gas outlet opening. A first high-frequency energy source supplies accelerating energy to a holder that supports a semiconductor specimen within the chamber to produce a high-frequency accelerating electric field. Gas is introduced to the chamber through the inlet opening and accelerated by the electric field toward the specimen. An antenna structure is connected to a second high-frequency energy source which supplies exciting energy at a frequency in the range between 100 MHz and 1 GHz which is higher than the frequency of the accelerating energy. The antenna structure has radially outwardly extending, circumferentially equally spaced apart elements of length equal to the quarter wavelength of the exciting energy so that there is a phase difference of 180 degrees between adjacent ones of the antenna elements. The accelerated gas is uniformly excited and converted to high-density plasma.

This apparatus comprises a vacuum chamber having a pumping system, a substrate holder for placing the substrate to be processed in the vacuum chamber, a gas introduction means for introducing the plasma generation gas into a plasma generation space, an energy supply means for supplying the RF energy with the plasma generation gas. The antenna has multiple antenna elements provided symmetrically to the center on the axis of the substrate and an end shorting member shorting each end of the antenna elements so that an RF current path symmetrical to the center is applied. Multiple circuits resonant at a frequency of the RF energy are formed symmetrically of the antenna elements and the end shorting member. Length obtained by adding total length of neighboring two of the antenna elements and length of the RF current path between ends of neighboring two of the antenna elements corresponds to one second of wavelength of the RF energy.

    摘要: In a monitoring method of monitoring status of a silicon layer etched in a hollow space by plasma, a chlorine including gas is introduced into a hollow space to cause CCl-radical to occur in the hollow space. A first spectrum region is selected to detect first emission spectra of the CCl-radical which are variable in intensity only during the etching and which may include a wavelength of 307 nm. Preferably, a second spectrum region is selected to second emission spectra invariable even during the etching and to indicate the beginning and the end of the etching by monitoring a relationship between the first and the second emission spectra. The second spectrum region may include a wavelength of 396 nm. Alternatively, emission spectra of OH-radical which results from water remaining in the hollow space may be monitored as the first emission spectra.
