US Patent 7238981 Metal-poly integrated capacitor structure

A metal-poly integrated capacitor structure that may be used in a charge pump circuit of a non-volatile memory. In one embodiment, the capacitor comprises a poly silicon layer, a first metal layer and a second metal layer. The first metal layer is positioned between the poly silicon layer and the second metal layer. The first metal layer has a first terminal and a second terminal. The first terminal is electrically isolated from the second terminal.
