发明名称 METHOD FOR FABRICATING FLASH MEMORY DEVICE
摘要 A flash memory device fabricating method can include forming a plurality of gate patterns over a semiconductor substrate, forming a first spacer over the semiconductor substrate and against sidewalls of each gate pattern and a second spacer over the first spacer, forming an impurity region in the semiconductor substrate and between respective gate patterns, removing the second spacer, and then forming a pre-metal dielectric film over the semiconductor substrate including the gate patterns and the first spacer. The second space can be removed in order to expand a space between the gate patterns to thereby prevent generation of voids between the gate patterns.
