摘要:
A non-volatile memory is provided. A plurality of stacked gate structure is formed on the substrate. The stacked gate structure includes, upward from the substrate surface, a select gate dielectric layer, a select gate and a cap layer. The spacers are disposed on the sidewalls of the stacked gate structures. The control gates are disposed over the substrate filling the space between the stacked gate structures and are mutually connected together. The floating gates are disposed between the stacked gate structures and positioned between the control gate and the substrate. The inter-gate dielectric layers are disposed between the control gates and the floating gates. The tunneling dielectric layers are disposed between the floating gates and the substrate. The source/drain regions are disposed in the substrate outside the two outermost stacked gate structures.
