Claim Text:
1. A semiconductor structure comprising a field effect transistor, said field effect transistor including: a tunnel dielectric comprising a first dielectric material having a dielectric constant greater than 8.0 and located on a semiconductor substrate; a floating gate electrode structure comprising at least a conductive material portion contacting said tunnel dielectric; a control gate dielectric located on said floating gate electrode structure and comprising a second dielectric material, wherein a vertical surface of said control gate dielectric is in physical contact with an edge of an interface between said conductive material portion and said tunnel dielectric; a control gate electrode structure located on said control gate dielectric, wherein a horizontal surface of said control gate dielectric is in contact with a top surface of said floating gate electrode, and a topmost surface of said control gate dielectric underlies, or is in physical contact with, a bottom surface of said control gate electrode; and another field effect transistor, said another field effect transistor including:
