ABSTRACT:
A method of manufacturing flash memory devices includes depositing a nitride film over a semiconductor substrate and forming an oxide film below the nitride film using an oxidization process involving an anneal process. A tunnel oxide film or an ONO2 oxide film having a thin thickness and a good film quality is formed and the operating performance of memory cells is improved.
