Nonvolatile semiconductor memory
A nonvolatile semiconductor memory according to an example of the present invention includes first and second diffusion layers, a channel formed between the first and second diffusion layers, a gate insulating film formed on the channel, a floating gate electrode formed on the gate insulating film, an inter-gate insulating film formed on the floating gate electrode, and a control gate electrode formed on the inter-gate insulating film. An end portion of the inter-gate insulating film in a direction of channel length is on an inward side of a side surface of the floating gate electrode or a side surface of the control gate electrode.
