Abstract
Embodiments relate to a three-dimensional flash memory cell and method of forming the same that may be improve the uniformity of flash memory cell by removing a width difference of a polysilicon pattern when forming a floating gate of flash memory device, to thereby improve the reliability of semiconductor device. The process may be simplified due to the self-alignment in the step of forming the polysilicon pattern, which may improve the yield.
