Abstract:
An object is to provide a semiconductor device having improved reliability by preventing, in forming a nonvolatile memory and MOSFETS on the same substrate, an increase in the size of grains in a gate electrode. The object can be achieved by forming the control gate electrode of the nonvolatile memory and the gate electrodes of the other MOSFETs from films of the same layer, respectively, and configuring each of the control gate electrode and the gate electrodes from a stack of two polysilicon film layers.
