Title: Vapor growth method
Inventor: NAKADA SABUROU
IPC: C23C16/458
Filed: 1982-05-14
Abstract: PURPOSE:To form uniform film thickness in the whole region of the surface of a semiconductor wafer by holding the whole one main surface of the wafer by a support board erected obliquely. CONSTITUTION:The round-shaped support boards 2 supporting the wafers of a boat are set up obliquely in the direction of an oven core, and round holes holding the whole backs of the wafers are formed among the support boards. Accordingly, excessive work for removing films on the backs is unnecessitated bacause films are hardly grown on the backs of the wafers. Since three substrates by projections through a conventional system are removed, a turbulence of a gas formed by obstacles is not generated, and the distribution of film thickness in case of growth is equalized. When a thin-film is formed by using SiH4 and O2 gas from a silicon oxide film through such a decompression vapor growth method, film thickness among the wafers is improved remarkably together with the distribution of film thickness in the wafers.
