A method of manufacturing a flash memory device which can improve capacitance and can reduce the interference phenomenon. According to one embodiment, a method of manufacturing a flash memory device includes the steps of depositing a tunnel oxide layer over a semiconductor substrate having a isolation structure, depositing a conductive layers for a floating gate over the tunnel oxide layer, forming an oxide layer between the conductive layers for the floating gate, forming a recess pattern in the conductive layers for the floating gate, and depositing a dielectric layer and a conductive layer for a control gate, respectively.
