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 1):
A semiconductor device comprising:\n a semiconductor substrate; a capacitor element formed over the semiconductor substrate, the capacitor element having a first region and a second region, the capacitor element including:\n first electrodes formed over the semiconductor substrate in the first region and extending in a first direction; \n a second electrode formed over the semiconductor substrate in the first region and extending in the first direction, the second electrode formed between the first electrodes disposed next to each other; \n a first insulating film formed between the semiconductor substrate and the second electrode and between the first electrodes and the second electrode respectively; and \n first plugs formed over the semiconductor substrate in the second region and electrically coupled to the semiconductor substrate in the second region, \n wherein the first region and the second region are arranged adjacent to each other in a second direction traversing the first direction, wherein the second region is for feeding electric potential to the first region.
