Abstract
A method of fabricating a nonvolatile memory device includes providing an intermediate structure in which a floating gate and an isolation film are disposed adjacent to each other on a semiconductor substrate and a gate insulating film is disposed on the floating gate and the isolation film, forming a conductive film on the gate insulating film, and annealing the conductive film so that part of the conductive film on an upper portion of the floating gate flows down onto a lower portion of the floating gate and an upper portion of the isolation film.
