Abstract
A method of manufacturing a flash memory device. According to the invention, a floating gate can be formed and a distance between cells can be secured sufficiently by using one conductive layer without using a SA-STI process that cannot be applied to the manufacturing process of highly integrated semiconductor devices. It is therefore possible to minimize interference between neighboring cells.
