Zusammenfassung: | A stacked-gate non-volatile memory cell includes a semiconductor substrate, a floating gate, a first spacer, a control gate, a second spacer, a first doped region and a second doped region. The floating gate is formed over the semiconductor substrate. The first spacer is contacted with a sidewall of the floating gate. The control gate is formed on a top side and a lateral side of the floating gate. The control gate is not contacted with the floating gate. The second spacer is contacted with a sidewall of the control gate. The first doped region and the second doped region are formed in the surface of the semiconductor substrate, and respectively located at two sides of the floating gate. |
