Title: Method of manufacturing thin film
Inventor: TSUJI NAOTO
IPC: C23C16/40
Filed: 2000-06-02
Abstract: PROBLEM TO BE SOLVED: To provide a technology by which the uniformity of film thickness of an SiO2 film can be improved in a plasma CVD method. SOLUTION: In the plasma CVD method, a thin film is formed on a substrate 21 by vapor growth by introducing a reaction gas prepared by mixing a TEOS gas and an O2 gas with each other into a vacuum tank 12 and decomposing the reaction gas by generating a plasma in a stable state while the pressure in the tank 12 is maintained lower than that in the conventional example, namely, between 70 Pa and 130 Pa. Consequently, since the concentration of radicals in the reaction gas in a vapor phase becomes lower and the mean free path of the radicals becomes longer, the radicals hardly come into collision with each other and, accordingly, hardly agglomerate. The film quality of the formed thin film becomes dense unlike the conventional example in which the film quality is deteriorated, because the radicals agglomerate and grow on the substrate 21 in a powdery state.
