  • Patent number: 9496327
    Abstract: A process of forming an integrated circuit forms a high precision capacitor bottom plate with a metallic surface and performs a plasma treatment of the metallic surface. A high precision capacitor dielectric is formed by depositing a first layer of the capacitor dielectric on the high precision capacitor bottom plate wherein the first layer is silicon nitride, depositing a second layer of the capacitor dielectric on the first layer wherein the second portion is silicon dioxide, and depositing a third layer of the capacitor dielectric on the second portion wherein the third layer is silicon nitride. Plasma treatments may also be performed on the layers of capacitor dielectric pre- and/or post-deposition. A metallic high precision capacitor top plate is formed on the high precision capacitor dielectric.

  • Publication number: 20160218062
    Abstract: An integrated circuit with copper damascene interconnects includes a thin film resistor. Copper damascene metal lines are formed in a first ILD layer. A dielectric layer including an etch stop layer is formed on the first ILD layer and metal lines. Resistor heads of refractory metal are formed in the dielectric layer so that edges of the resistor heads are substantially coplanar with the adjacent dielectric layer. A thin film resistor layer is formed on the dielectric layer, extending onto the resistor heads. A second ILD layer is formed over the dielectric layer and the thin film resistor layer. Copper damascene vias are formed in the second ILD layer, making contact to the metal lines in the first ILD layer. Connections to the resistor heads are provided by the metal lines and/or the vias.

  • Patent number: 8975135
    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.
