Title: Manufacture of semiconductor device
Inventor: NAKAMURA YASUO
IPC: H01L21/283
Filed: 1984-04-27
Abstract: PURPOSE:To decrease the frequency of the occurrence of the poor withstand voltage at the initial stage in a gate oxide film in a silicon MOS semiconductor device and to facilitate the control of the thickness of the oxide film, by performing heat treatment in the mixed atmosphere of oxygen and hydrogen, and thereafter performing heat treatment in an oxygen atmosphere. CONSTITUTION:In the process of forming a thermal oxide film on the surface of a semiconductor, heat treatment is performed in the mixed atmosphere of oxygen and hydrogen. Then, heat treatment is performed in an oxygen atmosphere. For example, the mixed gas including 3l/min of O2 and 3l/min of H2 is made to flow for the initial 3min, and the heat treatment is performed. Then only O2 is made to flow at a rate of 3.6l/min for 30min. Thereafter N2 is made to flow for a specified time. Thus a thermal oxide film is formed. A gate oxide film is formed on an Si wafer. Defects such as pinholes or micropores are not yielded in the thermal oxide film. Therefore, the occurrence of the poor withstand voltage at the initial stage is decreased. The rate of the treating time by the mixed gas of the oxygen and the hydrogen and the treating time of only the oxygen is adjusted. Thus the oxidizing time can be set at a suitable length. Especially, the control of the thickness of the thin oxide film becomes easy.
