Abstract
There is disclosed a method of manufacturing a flash memory device. In order to solve the problem that the coupling ratio of a gate electrode is low in a stack gate-type flash memory device, the present invention allows a control gate to surround a control gate from its to its bottom. Therefore, the present invention can increase the contact area of the floating gate and the control gate and can also increase the coupling ratio of the gate electrode.
