Abstract: An analog floating-gate electrode in an integrated circuit, and method of fabricating the same, in which trapped charge can be stored for long durations. The analog floating-gate electrode is formed in a polycrystalline silicon gate level, and includes portions serving as a transistor gate electrode, a plate of a metal-to-poly storage capacitor, and a plate of poly-to-active tunneling capacitors. A silicide-block film comprised of a layer of silicon dioxide underlying a top layer of silicon nitride blocks the formation of silicide cladding on the electrode, while other polysilicon structures in the integrated circuit, such as polysilicon-to-metal capacitors, are silicide-clad. Following silicidation, a capacitor dielectric is deposited over the remaining polysilicon structures, followed by formation of an upper metal plate.
