摘要： A radio frequency power supply structure and a plasma CVD device comprising the same are provided in which reflection of radio frequency power at a connecting portion where an RF cable connects to an electrode is reduced so that incidence of the radio frequency power into the electrode increases. In the radio frequency power supply structure for use in a device generating plasma by charging a plate-like electrode with a radio frequency power, the radio frequency power supply structure supplying the electrode with the radio frequency power from an RF cable, the RF cable is positioned on an extended plane of a plane formed by the electrode to connect to the electrode at a connecting portion provided on an end peripheral portion of the electrode. The RF cable connects to the electrode substantially in the same plane as the plane formed by the electrode. Voltage acting after the connecting portion becomes symmetric relative to the plane formed by the electrode and the electric line of force also becomes symmetric. Thereby, change of impedance at the connecting portion is reduced, reflection of the radio frequency power at the connecting portion is reduced, incidence of the radio frequency power into the electrode increases and the efficiency of film forming and surface treatment is enhanced.

摘要： A method for making the characteristics of the distribution of film thickness uniform is provided, avoiding generation of phase differences among streams of high-frequency electric power by manipulating the electrical characteristics of cables through which the high-frequency electric power is transmitted. Coaxial cables (19a to 19h and 24a to 24h) having a standard length and vacuum cables (20a to 20h and 25a to 25h) are installed, then a film is formed on a substrate by actually supplying high-frequency electric power, and thereafter the condition of vapor deposition such as the thickness of the film is observed. Based on the observations, the full lengths of the coaxial cables which communicate with the feeding points and the electrodes which correspond with positions over the substrate which need to be adjusted are changed. The coaxial cables are installed again, and high-frequency electric power equivalent to that used in the previous operation is supplied to form a film. The distribution of the film formed on the substrate is made uniform by repeating the above operations.

摘要： An object is to provide a high-frequency plasma generating apparatus and process which can further advance uniformity of the thickness of a film on a substrate with a large area in comparison with conventional apparatuses. In a reaction chamber (1), a ground electrode (3) is disposed, and a discharge electrode (2) is disposed opposite to the ground electrode (3). A substrate (4) as a processing object is placed in close contact with the ground electrode (3). A high-frequency voltage is applied to the discharge electrode (2) so as to generate plasma between the ground electrode and the discharge electrode. An RF electric power supply (15) generates a first high-frequency voltage, and outputs the generated voltage on feeding points (9) disposed on a lateral portion of the discharge electrode (2). An RF electric power supply (16) generates a second high-frequency voltage, and outputs the generated voltage on feeding points (9) disposed on another lateral portion of the discharge electrode (2). Here, the second high-frequency voltage has the same frequency as that of the first high-frequency voltage and has a phase which varies with a low-frequency signal, which is modulated by a predetermined modulation signal.

摘要： An object is to provide apparatuses for plasma processing which can make the distribution of the film thickness of a substance on a substrate uniform, methods of processing a substrate therewith, apparatuses for plasma-enhanced chemical vapor deposition, and methods for film formation therewith. When a desired substance is vapor deposited on the surface of a substrate (3), characteristics of the distribution of the thickness of a film on the substrate having a large area are improved by eliminating local imbalance in the distribution of the film thickness originating from deviation in the distribution of voltage on the ladder electrode (2), by way of adjusting impedance matching between each coaxial cable and corresponding feeding point for the ladder-shaped electrode (2) using branch cables provided to the coaxial cables for supplying high-frequency electric power to a ladder-shaped electrode (2) so as to make the film thickness uniform in the direction at right angles with the direction of fed electric power, whereby high-frequency electric power which is fed to each longitudinal electrode rod (2a) of the ladder-shaped electrode (2) can be adjusted, and distribution of voltage at a right or left part of the substrate and distribution of voltage at a central part of the substrate can be balanced, as well as by way of promoting uniformity in the distribution of the film thickness in the direction of fed electric power, by supplying streams of high-frequency electric power having the same frequency from two power supplies to the ladder-shaped electrode (2) with the phase difference between the high-frequency electric powers being varied over time.

摘要： An apparatus and method for treating exhaust gases. In this apparatus, a plurality of stages of reactor chambers (R.sub.1, R.sub.2, . . . . and R.sub.n) are connected in series in the direction of an exhaust gas flow. Further, high-voltage power supplies (V.sub.1, V.sub.21 . . . and V.sub.n) are connected to the reactor chambers (R.sub.1, R.sub.2, . . . . and R.sub.n), respectively. Moreover, in each of these reactor chambers, a streamer discharger plasma is generated. Furthermore, the more downstream a reactor chamber of a stage is placed, the lower energy to be cast into the reactor chamber becomes. The density of electrons generated in a gas decomposition unit is high in a portion thereof on the upstream side of the exhaust gas flow and the electron density is low in a portion thereof on the downstream side. Additionally, the present invention further provides a pulse generator in which a high voltage, which is an output voltage of a D.C. charger (V.sub.0), is simultaneously applied to a plurality of distributed constant lines (or transmission lines) (1.sub.-1, 1.sub.-2, 2.sub.-1, 2.sub.-2, . . . , N.sub.-1 and N.sub.-2), which are connected in parallel with one another, by means of a signal shortcircuit switch (S.sub.1).
