IPC: G03G5/08
Filed: 1986-09-27
Abstract: PURPOSE:To obtain a sensitive body having high dark resistivity by decomposing a gas contg. C2H2 and Si in a prescribed ratio and a gas for forming amorphous silicon carbide (a-SiC) contg. a prescribed amount of a group Va element of the periodic table by glow discharge to form a negatively chargeable layer on a substrate. CONSTITUTION:A first layered region 6 and a second layered region 7 are successively formed on an electrically conductive substrate 1 in the form of an integrated photoconductive a-SiC layer 5a. The first region 6 contains a larger amount of a group Va element than the second region 7. In order to form the a-SiC layer 5a, a gas contg. C2H2 and Si in 0.01:1-3:1 ratio and 0-1mol% gas contg. the group Va element are used. The second region 7 contains 0-10,000ppm, preferably 0-1,000ppm group Va element, so the resulting sensitive body is negatively chargeable and required electrophotographic characteristics such as surface potential and photosensitivity are obtd. Since light carriers generated in the a-SiC layer 5a flow smoothly to the substrate 1 by the presence of the first region 6, the photosensitivity is improved.

Filed: 1995-09-06
Abstract: PROBLEM TO BE SOLVED: To form a capacitance insulating film containing a silicon nitride film which is free from deterioration of film quality and excellent in leak characteristics. SOLUTION: After a poly silicon film is formed on a silicon oxide film 2 on a silicon substrate 1 and doped with phosphorus, a lower layer poly silicon film 3 is formed by patterning a specified part of the poly silicon film. After a silicon nitride film 4 is formed on the poly silicon film 3, heat treatment is performed in a nitrogen suboxide atmosphere at 1000 deg.C. After a poly silicon film is formed on the whole of the silicon nitride film 4 subjected to the heat treatment in the nitrogen suboxide atmosphere and doped with phosphorus, an upper layer poly silicon film 5 is formed by patterning a specified part of the poly silicon film. As the result of heat treatment of the silicon nitride film 4 in the nitrogen suboxide atmosphere, unstable traps in the silicon nitride film 4 are not generated, and the increase of a leakage current can be effectively restrained.
