Abstract
A semiconductor structure includes a substrate, a dielectric structure, a floating gate, and a control gate. The substrate has a protrusion, a first recess, and a second recess, wherein the first recess and the second recess are on opposite sides of the protrusion. The dielectric structure extends from the first recess and the second recess to above a top surface of the protrusion. The floating gate is disposed over the substrate and adjoins a sidewall of the dielectric structure. The control gate is disposed over the floating gate and extends over a top surface of the dielectric structure to directly above the protrusion.
