Abstract: The present invention provides a receiver that includes a plurality of tuners for receiving broadcasts such as satellite broadcast. A tuner circuit (1) includes an input terminal (11) for inputting a broadcast wave in which a video signal and/or an audio signal are modulated in a predetermined format, and a mount layer (13) on which a main circuit (12) for selecting, from the broadcast wave, a video signal and/or an audio signal included in a predetermined frequency band is mounted. In the tuner circuit (1), a first ground layer (15) is disposed, through a first dielectric layer (14), on the surface opposite to that on which the main circuit (12) of the mount layer (13) is arranged, and a second ground layer (17) is disposed through a second dielectric layer, thereby suppressing mutual interference between tuners.

Abstract: The upper electrode (15a) and the lower electrode (15b) are installed in the chamber (2) in parallel. Between these electrodes, the upper electrode (15a) is electrically grounded. The lower electrode (15b) is connected to the first RF power generator (13) via the low-pass filter (14) and to the second RF power generator (22) via the high-pass filter (23). Wafer W is held against the upper part of the lower electrode (15b) by the high-temperature electrostatic chuck ESC. By being distributed the first and the second RF electric power from the RF power generators (13) and (22), respectively, plasma is produced near the lower electrode (15b), and the wafer W is processed by the plasma. By these procedures, plasma process apparatus with high efficiency in plasma processing and simple structure can be offered.

Abstract: A probe (6) is brought into contact with a plasma produced by ionizing Ar gas, a saturation current (Ies2) at which current flowing through the probe is saturated when the potential of the probe is changed in a potential region where the potential of the probe is higher than a ground potential, and a saturation current (Iis2) at which current flowing through the probe is saturated when the potential of the probe is changed in a potential region where the potential of the probe is lower than the ground potential. Similarly, saturation currents (Ies2, Iis2) are measured by bringing the probe (6) into contact with a plasma produced by ionizing a mixed gas containing Ar gas and a process gas, such as C4F8 gas, and changing the potential of the probe (6). The negative ion density of the plasma produced by ionizing C4F8 gas is determined by using saturation current ratios (Iis1/Iis2, Ies1/Ies2).

Abstract: The present invention aims to decrease reflected waves in a vacuum chamber to suppress standing waves, thereby easily controlling a plasma density so that uniform treatment can be performed. An electromagnetic wave absorber 6 composed of a resistor such as carbon, a dielectric having a large dielectric loss, such as water, or a magnetic material such as ferrite-based ceramic, or a combination of these, is provided on an inner wall surface of a first vacuum chamber 21.

Abstract: An electron density at an ECR point, which is spaced from a substrate to be treated and which faces the substrate, is set to be higher than or equal to 0.46 nc (nc: an upper limit side cut-off density of an X wave) and lower than nc. Thus, a high chevron distribution of electron density is formed in end portions of a magnetic field forming region, and a distribution of electron density having a lower peak value than those in the end portions is formed in a central portion of the magnetic field forming region. In this case, the periphery of a magnetic field crosses the inner wall of a vacuum chamber once between the ECR point and the substrate, and a space of one fourth or more of the wavelength of the X wave is formed between the periphery of the magnetic field and the inner wall of the vacuum chamber as the magnetic field runs downstream. Thus, it is possible to achieve an inplane uniform treatment when carrying out a treatment, such as a thin film deposition or etching, with ECR plasmas for a wafer.

A grounding circuit which discharges electric charges remaining on the susceptor is disposed in parallel with an RF power supply circuit which supplies RF power to the susceptor. Thus, electric charges remaining in the power supply circuit can be discharged and an abnormal discharging between the push-up pin and the susceptor can be prevented.
