A select gate of a NAND memory array has a first dielectric layer formed
on a semiconductor substrate. A first conductive layer is formed on the
first dielectric layer. Conductive spacers are formed on sidewalls of the
first conductive layer and are located between an upper surface of the
first conductive layer and the first dielectric layer. A second
dielectric layer overlies the first conductive layer and the conductive
spacers. A second conductive layer is formed on the second dielectric
layer. A third conducive layer is formed on the second conductive layer,
passes though a portion of the second conductive layer and the second
dielectric layer, and contacts the first conductive layer. The third
conductive layer electrically connects the first and second conductive
layers.
