Abstract:
A method of fabricating a flash memory includes forming a first oxide film over a semiconductor substrate, forming a metal film over the first oxide film, forming a photoresist pattern on the metal film, etching the metal film using the photoresist pattern as a mask and forming a metal film pattern, forming a second oxide film overlying the metal film pattern, and heat-treating the first and second oxide films at high temperature and processing the metal film pattern using metal oxide crystallization.
