摘要:
The present invention is directed to a method for forming a thin film on a substrate by the use of a glow discharge plasma which comprises generating a magnetic field in a direction which crosses an electric field for discharge at right angles and fluctuating the magnetic field. The present invention is also directed to an apparatus for practicing the above method, which apparatus is composed of a reaction vessel, means for reducing the pressure in the reaction vessel and means for introducing the feed of reaction gases to the reaction vessel, electrodes for discharge disposed face to face in the reaction vessel, a power source from which a voltage for causing a glow discharge is fed to the electrodes for discharge, a coil surrounding the electrodes for discharge, for generating a magnetic field in a direction crossing at right angles to an electric field generated between the electrodes for discharge, and an AC power source for generating a magnetic field fed to the coil, whereby a thin film is formed on a base plate supported outside the range of the discharge electric field and in parallel with the direction of the electric field.
摘要:
An apparatus and method for treating exhaust gases. In this apparatus, a plurality of stages of reactor chambers (R1, R2, . . . Rn) are connected in series in the direction of an exhaust gas flow. Further, high-voltage power supplies (V1, V2, . . . and Vn) are connected to the reactor chambers (R1, R2, . . . and Rn), 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 (V0), is simultaneously applied to a plurality of distributed constant lines (or transmission lines) (1−1, 1−2, 2−1, 2−2, . . . , N−1 and N−2), which are connected in parallel with one another, by means of a signal shortcircuit switch (S1).

An amorphous silicon solar cell includes a substrate, a transparent electrode formed on this substrate, a power-generating film formed on this transparent electrode, and a back-side electrode formed on this power-generating film. The power-generating film is formed by sequentially stacking p-type/i-type/n-type hydrogenated amorphous silicon layers. The defect density of the i-type hydrogenated amorphous silicon layer is less than 1015 defects/cc.

摘要:
A liquid crystal device is constituted by a pair of substantially parallel substrates disposed opposite to each other to leave a gap extending two-dimensionally therebetween including a rectangular wider gap region and a peripheral frame-shaped narrower gap region surrounding the wider gap region, a plurality of spacers disposed in the gap over the wider and narrower gap regions, and a liquid crystal disposed between the pair of substrates so as to form pixels in the wider gap region. The spacers are disposed to have a larger volume per unit substrate area in the wider gap region and a smaller volume per unit substrate area in the narrower gap region, thus providing a uniform cell gap between the substrates.
摘要:
A plasma CVD apparatus whose discharge electrode is a single line member bent in a U shape in an alternating manner and in which a substrate to be processed is held substantially in parallel to the discharge electrode. The electric field around the electrode becomes stronger and the intensity distribution of this field becomes even. As a result, a product film formed on the substrate surface has a uniform thickness, and the film can be formed at high speeds.
