Abstract:
The improvement of the reliability of a semiconductor device having a split gate type MONOS memory is implemented. An ONO film and a second polysilicon film are sequentially formed so as to fill between a first polysilicon film and a dummy gate electrode. Then, the dummy gate electrode is removed. Then, the top surfaces of the first and second polysilicon films are polished, thereby to form a memory gate electrode formed of the second polysilicon film at the sidewall of a control gate electrode formed of the first polysilicon film via the ONO film. As a result, the memory gate electrode high in perpendicularity of the sidewall, and uniform in film thickness is formed.

Claim (Index 5):
The semiconductor device according to  claim 1 ,\n wherein a part of the first electrodes extending in the second direction.
