发明名称 Method of fabricating flash memory device
摘要 A flash memory device including a cell region and a logic region formed over a semiconductor substrate; a pair of stacked gates formed spaced apart over the cell region; a pair of first spacers formed over the cell region in direct contact with at least one side of the stacked gates; a pair of gate electrodes formed spaced apart over the logic region; a pair of second spacers formed over the logic region in direct contact with at least one side of the gate electrodes; a first photoresist layer formed over the cell area between the first spacers and a second photoresist layer formed over the logic area between the second spacers, the second photoresist layer having a predetermined thickness sufficient to protect the second spacers.
