Abstract
A semiconductor device includes a semiconductor substrate, a tunnel dielectric disposed on the semiconductor substrate, a floating gate disposed on the tunnel dielectric, a control gate disposed on the floating gate, and an insulation layer disposed between the floating gate and the control gate. The semiconductor device further includes a spacer continuously distributed on the sidewall surfaces of the floating gate and the control gate, and the spacer overlaps portions of the top surface of the floating gate.
