Title: Manufacture of semiconductor device
Inventor: TAJIMA KAZUHIRO
IPC: H01L21/316
Filed: 1989-07-21
Abstract: PURPOSE:To enhance the evenness of film thickness while assuring the breakdown strength characteristics of oxide films by a method wherein the first oxide film in almost even thickness is formed on a semiconductor substrate by rapid heating and short time oxidation processes and successively the second oxide film in arbitrary thickness is formed by the same processes in the same reaction chamber. CONSTITUTION:Firstly, the first oxide film in excellent evenness of film thickness is formed by rapid heating and short time oxidizing an oxide film on a silicon substrate at relatively low temperature of 750-850 deg.C. Next, the second oxide film in arbitrary thickness is formed by performing the normal rapid heating and short time oxidizing processes continuously at the high temperature of 1100-1200 deg.C in the same reaction chamber as that wherein the said rapid heating and short time oxidizing processes are performed so that the film thickness may be proportional to the oxidation time raised to 1/2 power in no danger of accelerating the initial oxidation rate in the oxidation process since the first oxide film is previously formed in the oxidation process of the second oxide film. Accordingly, the oxidation process is advanced while assuring the evenness of the oxide film thickness. Furthermore, the break-down strength characteristics in high reliability can be displayed due to the second rapid heating and short time oxidation processes successively performed.
