Memory devices and methods of manufacturing the same
摘要:
The memory device includes upper gate structures and lower gate structures formed on an active region of a substrate, and an insulation layer. Each of the upper gate structures may have a blocking layer pattern and a control gate electrode. Each of the lower gate structures may have a tunnel insulation layer pattern and a floating gate electrode. The floating gate electrode may include a lower portion that is narrower than an upper portion contacting with the upper gate structure. The insulation layer may cover gate structures formed of the lower and upper gate structures, and may include air gaps between adjacent gate structures.
