Title: Formation method of insulating film
Inventor: FUKUDA HISASHI
IPC: H01L21/316
Filed: 1991-02-07
Abstract: PURPOSE:To form a fine oxide insulating film with few defects. CONSTITUTION:A silicon substrate 12 preoxidation-cleaned up is arranged in a reaction furnace 14. Next, H2 gas as a reducing gas led in the reaction furnace 14 is RF plasma discharged to remove a natural oxide film and impurities on the substrate 12. Next, O2 gas as an oxidizing gas is led in the reaction furnace 14 while holding the substrate in the reaction furnace 14 as it is so that the O2 gas may be RF discharged to form a thermal oxide film on the substrate 12. At this time, the substrate 12 is heated by an infrared ray lamp 18. On the other hand, since the O2 gas is activated by the RF plasma discharging step while heating the substrate 12 by infrared ray irradiation so as to efficiently accelerate the reaction between the substrate constituent Si and the oxide gas component atom O, the uncoupled bond of substrate constituent Si can be reduced thereby enabling said purpose to be attained.
