Abstract: PURPOSE: A method of manufacturing a flash memory cell is provided to prevent increase of leakage current due to concentration of electric field by minimizing grain boundary density. CONSTITUTION: A tunnel oxide layer(102) and the first silicon layer(103) are sequentially formed on a semiconductor substrate(100). SPG(Solid Phase Growth) annealing is performed in the first silicon layer to minimize grain boundary density over the tunnel oxide layer.
