Abstract

A semiconductor device having plural memory cell regions featuring nonvolatile memory cells, each nonvolatile memory cell including a first insulating film formed over a semiconductor substrate, a control electrode formed over the first insulating film, the first insulating film acting as a gate insulator for the control gate electrode, a second insulating film formed over the semiconductor substrate, and a memory gate electrode formed over the second insulating film and arranged adjacent with the control gate electrode through the second gate insulating film, the second insulating film acting as a gate insulator for the memory gate electrode and featuring a non-conductive charge trap film, wherein each of the nonvolatile memory cells of a first memory cell region and each of the nonvolatile memory cells of a second memory cell region are formed adjacent to one another such that a drain region is shared between them.
