A method for manufacturing a semiconductor device that comprises forming
an oxide layer over a substrate. A polysilicon layer is disposed
outwardly from the oxide layer, wherein the polysilicon layer forms a
floating gate. A PSG layer is disposed outwardly from the polysilicon
layer and planarized. The device is pattern etched to form a capacitor
channel, wherein the capacitor channel is disposed substantially above
the floating gate formed from the polysilicon layer. A dielectric layer
is formed in the capacitor channel disposed outwardly from the
polysilicon layer. A tungsten plug operable to substantially fill the
capacitor channel is formed.
