摘要： A semiconductor memory device comprises a plurality of transistors having a stacked-gate structure. Each transistor includes a semiconductor substrate, a gate insulator formed on the semiconductor substrate, a lower gate formed on the semiconductor substrate with the gate insulator interposed, an intergate insulator formed on the lower gate, and an upper gate formed and silicided on the lower gate with the intergate insulator interposed. A portion of the transistors has an aperture formed through the intergate insulator to connect the lower gate with the upper gate and further includes a block film composed of an insulator and formed smaller than the upper gate and larger than the aperture above the upper gate to cover the aperture.

摘要： A semiconductor device includes first and second gate electrodes arranged adjacent to each other, an oxide film formed between the first and second gate electrodes, and a nitride film formed on control gates and upper surfaces and sidewalls of the oxide film. Each of the first and second gate electrodes has a stacked gate structure which has a first insulating film, charge storage layer, second insulating film and control gate stacked on a semiconductor substrate. The uppermost surface of the oxide film is set higher than the uppermost surface of the control gate.
