Method of manufacturing a flash memory cell |
| abstract |
The present invention relates to a method of manufacturing a flash memory cell. A tunnel oxide film is formed before a trench is formed and an exposed portion is then etched by a given thickness. Therefore, a phenomenon that the corner of the trench is thinly formed by a sidewall oxidization process is prevented and an active region of a desired critical dimension can be secured. |
