SEMICONDUCTOR DEVICE INCLUDING A P-CHANNEL TYPE MOS TRANSMITTER

摘要

A method of manufacturing a semiconductor device including a stacked gate type nonvolatile memory cell and a p-channel type first transistor, includes: forming a gate insulating film of the first transistor on a semiconductor substrate; forming a tunnel insulating film of the stacked gate type nonvolatile memory cell on the semiconductor substrate; forming a first conductive layer containing an n-type impurity on the tunnel insulating film and the gate insulating film; and implanting p-type impurity ions to a region of the first conductive layer for forming the first transistor to turn the region of the first conductive layer into a p-type region.
