发明名称 Semiconductor memory devices including recess-type control gate electrodes and methods of fabricating the semiconductor memory devices
摘要 A semiconductor memory device includes a semiconductor substrate, a control gate electrode recessed in the semiconductor substrate, a storage node layer interposed between a sidewall of the control gate electrode and the semiconductor substrate, a tunneling insulation layer interposed between the storage node layer and the semiconductor substrate, a blocking insulation layer interposed between the storage node layer and the control gate electrode, and first and second channel regions formed around a surface of the semiconductor substrate to at least partially surround the control gate electrode. The semiconductor memory device may include a plurality of control gate electrodes, storage node layers, tunneling insulation layers, blocking insulation layers, and continuous first and second channel regions. A method of fabricating the semiconductor memory device includes etching the semiconductor substrate to form a plurality of holes, forming the tunneling insulation layers, storage node layers, blocking insulation layers, and control gate electrodes.
