Title: Semiconductor device manufacturing method
Inventor: EGASHIRA KYOKO
IPC: H01L21/302
Filed: 1991-07-17
Abstract: PURPOSE:To completely remove a contamination organic matters on the surface and prevent breakdown strength deterioration of the oxidized film by a method wherein, after a resist layer formed on a thin oxidized film is removed, oxidization treatment is performed to the surface of the oxidized film. CONSTITUTION:A LOCOS is formed on a p-type silicon substrate to define an element region to form a gate oxidized film on the element region. After a positive resist is applied on the oxidized film, a high frequency electric field is applied to introduced oxygen gas with a plasma-screening asher to produce an oxygen plasma by which the resist is removed. Thereafter, the surface of the gate oxidized film is treated with a UV irradiation and an O3 introduction. Thus, contamination organic matters on the surface can completely be removed and breakdown strength deterioration of the oxidized film can be prevented. Accordingly, it is possible to enhance the manufacturing yield and reliability of the semiconductor device.
