Technical Examples

Reliability of a semiconductor device having a nonvolatile memory comprising first through third gate electrodes is enhanced. With a flash memory having first gate electrodes (floating gate electrodes), second gate electrodes (control gate electrodes) and third gate electrodes, isolation parts are formed in a self-aligned manner against patterns of a conductor film for forming the third gate electrodes by filling up the respective isolation grooves and a gate insulator film for select nMISes in a peripheral circuit region is formed prior to the formation of the isolation parts. By so doing, deficiency with the gate insulator film for the select nMISes, caused by stress occurring to the isolation parts, can be reduced. Further, with the semiconductor device including the case of stacked memory cells, the patterns of the conductor film for forming the third gate electrodes, serving as a mask for forming the isolation parts in the self-aligned manner, can be formed without misalignment against channels.
