摘要 |
An interlayer insulating film is formed by the CVD method to cover a side surface of lower floating gate, and the top surface of said interlayer insulating film is planarized. An upper floating gate is formed extending over lower floating gate and interlayer insulating film. A control gate is formed on upper floating gate with an insulating film therebetween.
