摘要:
A method for forming an amorphous semiconductor thin film on a substrate, which comprises preparing a reactor fitted with at least a high-frequency electrode for generating glow discharge, applying an A.C. voltage to the electrode, applying a D,.C. voltage to the electrode independently from the A.C. voltage, feeding a reactive gas into the reactor to generate glow discharge of the reactive gas and maintain it, and forming the semiconductor thin film on the substrate.

A transparent panel heater which can be used for example for heating a window portion of liquid crystal displays, refrigerated showcases, freezer showcases, and defrosters of windshields, has a transparent substrate (2), a transparent conductive film (3) formed on the substrate (2), a substantially light-transmittable metallic electrode-underlying-layer (4) formed on the transparent conductive film (3) and on which layer (4) a pair of metallic electrodes (5) are provided for electrifying the conductive film (3); the latter is a laminate of at least one transparent thin layer (3b) made of a nitride and/or a carbide and at least one substantially light-transmittable metallic layer (3c). The transparent conductive film (3) and electrode-underlying-layer (4) are preferably formed by a dry process, while the electrodes (5) are preferably formed by a wet-plating method.

A planar reflector is composed of a base (8) and a flexible substrate (5) having a high reflection layer (6) formed thereon and overlayed on the base (8) with an adhesive layer (7) interposed between the high reflection layer and the base. The adhesion strength between the base and the substrate is at least 100 g/cm, and the thickness of the adhesive layer is not smaller than 0.5 µm but not greater than 50 µm. A curved reflector can be obtained by bending the planar reflector so that a curved surface having a curvature of radius not greater than 5 mm is formed presenting a concave surface on a side of the flexible substrate.

A film-forming apparatus comprising a high-frequency application electrode (10) and an earth electrode (20). The high-frequency applying electrode has an uneven surface with hills (50) and valleys (60). An amorphous silicon film is formed uniformly on a substrate (40) at a high speed by feeding a silicon-based gas into this apparatus and generating a glow discharge between the high-frequency application electrode (10) and the earth electrode (20), and positioning the substrate (40) in an atmosphere of the generated glow discharge.
摘要:
A transparent conductive laminate in which a transparent conductive layer (an ITO film) mainly comprising indium, tin and oxygen is formed on one main surface of a transparent substrate such as a polymeric film and which is excellent in moist heat resistance and scuff resistance and which can be applied to various kinds of transparent electrodes. The transparent conductive layer has a stable amorphous structure, and its resistivity is 1x10 -2 Ω·cm or less, and its electron mobility is 20 cm 2 /(V·sec) or more. This transparent conductive laminate can be prepared by forming an amorphous film mainly comprising indium, tin and oxygen and having a resistivity of more than 1x10 -2 Ω·cm on the substrate by a sputtering process under a high oxygen concentration atmosphere, and then subjecting the film to a heat treatment in the range of 80 to 180 °C to decrease the resistivity to 1x10 -2 Ω·cm or less, while the amorphous structure is maintained. This transparent conductive laminate can suitably be utilized as the transparent electrode of an electroluminescence light-emitting element equipped with a layer containing zinc sulfide as a light-emitting layer, and in this case, the deterioration of luminance during continuous light emission can be remarkably inhibited.
