Inventor: FUKUDA HISASHI
IPC: H01L21/76
Filed: 1988-11-07
Abstract: PURPOSE:To reduce a stress generated when an element isolation region is formed by a method wherein a first oxide film is grown on the surface of polysilicon by a rapid thermal oxidation treatment and a second oxide film is deposited on the surface of the first oxide film. CONSTITUTION:A substratum is processed by a rapid thermal oxidation treatment; a first oxide film 31 is formed on the surface of a polysilicon layer 27. The rapid thermal oxidation treatment is a treatment by which a semiconductor substrate as an object to be heat-treated is heated in an atmosphere of dry oxygen for a duration of about 10 seconds up to a temperature of 1000 deg.C or higher. When a rapid heat-treatment apparatus is used in this manner, only the surface of the object to be heat-treated can be heated; accordingly, the time required to raise a temperature and to lower the temperature can be shortened. After the first oxide film 31 has been grown, a second oxide film 33 is deposited; thereby, a cap oxide film 35 is formed. Accordingly, it is possible to reduce a bird's beak; in addition, when the cap oxide film 35 having a sufficient film thickness is formed, a crystal defect is not caused in silicon in an element region.
