摘要：
A semiconductor memory device manufacturing method includes forming a floating gate electrode above a semiconductor substrate, forming an interelectrode insulating film above the floating gate electrode, forming a first radical nitride film on a surface of the interelectrode insulating film by first radical nitriding, and forming a control gate electrode on the first radical nitride film.
