A primary cell source ion-implantation process is performed to form a cell source, and then the first spacer(18) is formed on an etching surface of the cell area and the peripheral circuit area. A self align source etching process and a secondary cell source ion-implantation process are performed to form a source line, and then an annealing process is performed. An exposed part of the first polysilicon layer being twice etched is removed by the secondary self align etching process, a stack gate part of a drain(19) side is determined, and thus a stack gate comprised of a floating gate and a control gate is completed. A cell drain is formed by a cell source/drain ion-implantation process.
