发明名称 Method of fabricating a flash memory
摘要 A method of fabricating a flash memory provides a substrate having a tunnel oxide layer, a first conductive layer and a first material layer thereon. A conductive spacer is formed on the sidewalls of the first conductive layer and the first material layer. A second material layer is formed on the substrate. A portion of the second material layer is removed, until a part of the conductive spacer has been exposed. The remaining portion of the second and first material layers are removed, to expose the first conductive layer and the conductive spacer. The first conductive layer and the conductive spacer, together then form a floating gate. A dielectric film layer is then formed on the substrate, and a second conductive layer is subsequently formed above the dielectric film layer.
