摘要： This invention relates to a fluorine-containing amorphous carbon film with benzene rings distributed therein. The film is formed by plasma CVD while using an aromatic hydrocarbon gas and a fluoride gas as raw materials. This invention is also concerned with a semiconductor layer which features use of the fluorine-containing amorphous carbon film as an interlayer insulating film. The fluorine-containing amorphous carbon film has a low specific dielectric constant, does not contain much intrafilm water and is superior in heat resistance, so that the fluorine-containing amorphous carbon film permits application of a known conductive-pattern-forming process, which requires heat treatment at elevated temperature, and can provide a semiconductor device with reduced signal delays.

摘要： A groove (4) is formed on the surface of a silicon substrate (1) by way of etching. A silicon device (3) for a driver of a photosensitive element is formed on the surface of the substrate (1) where the groove (4) is not formed. With the groove, a super lattice structure (6) of Si and Si 1-x Ge x is buried to form a photosensing portion (2). The photosensing portion is formed with an avalanche photodiode or a PIN diode. The photosensing portion is formed to have no step with the surface of the substrate. On the other hand, SOI silicon oxide layer is provided on the back side of the substrate to form the structure of SOI substrate. By this, a photo reflection layer (7) of SiO₂ layer is provided below the photosensing portion (2). Thus, a silicon type photosensing element and the silicon device for driver can be formed on a common chip simultaneously for reducing production cost and for improving sensitivity and photo converting efficiency of the photosensing element.

摘要： In a method of forming an amorphous carbon thin film with a plasma chemical vapor deposition method, at least one of a hydrocarbon gas and a carbon fluoride gas is supplied in a reaction chamber as a material gas. By applying a high voltage between two electrodes, a plasma is generated in the reaction chamber using the supplied material gas. In order to prevent the adhesion from depositing on the inner wall, at least a part of the inner wall of the reaction chamber is heated to a predetermined temperature or above such that an adhesion coefficient of the adhesion is 0. Alternatively, in order to prevent the adhesion from depositing on the inner wall, a bias voltage such as one of DC bias, a high frequency bias and a high frequency bias imposed on a DC bias is applied to the electrically conductive reaction chamber.

The poly-crystalline silicon layer has an uneven surface including a plurality of convex portions and a plurality of concave portions, with said convex portions being defined by growing silicon grains, such as hemisherical-like silicon grains, or mushroom-like silicon grains, projecting from the surface of the silicon layer. A typical silicon grain has a diameter in range of 30 to 170nm.

摘要： A method for fabricating a polycrystalline silicon having a roughed surface, which is useful for a capacitor electrode is disclosed. The method is featured by depositing a polycrystalline silicon layer in such a manner that grains of silicon are caused at the surface of the polycrystalline silicon layer. The polycrystalline silicon layer thus obtained has a large effective surface area and is suitable for a capacitor electrode because of its increased effective surface area.
