    摘要: A resistor layout and method of forming the resistor are described which achieves improved resistor characteristics, such as resistor stability and voltage coefficient of resistance. A resistor is formed from a conducting material such as doped silicon or polysilicon. The resistor has a rectangular first resistor element, a second resistor element, a third resistor element, a fourth resistor element, and a fifth resistor element. A layer of protective dielectric is then formed over the first, second, and third resistor elements leaving the fourth and fifth resistor elements exposed. The conducting material in the exposed fourth and fifth resistor elements is then changed to a silicide, such as titanium silicide or cobalt silicide, using a silicidation process. The higher conductivity silicide forms low resistance contacts between the second and fourth resistor elements and between the third and fifth resistor elements. The second and third resistor elements are wider than the first resistor element and provide a low resistance contacts to the first resistor element, which is the main resistor element. This provides low voltage coefficient of resistance thermal process stability for the resistor.

A contact node is provided overlying a semiconductor substrate. An intermetal dielectric layer is deposited overlying the contact node. A damascene opening is formed through the intermetal dielectric layer to the contact node. A first metal layer is formed on the bottom and sidewalls of the damascene opening and overlying the intermetal dielectric layer. A first barrier metal layer is is deposited overlying the first metal layer. A dielectric layer is dpeosited overlying the first barrier metal layer. A second barrier metal layer is deposited overlying the dielectric layer. A second metal layer is formed overlying the second barrier metal layer and completely filling the damascene opening. The layers are polished back to leave the first metal layer, the dielectric layer, the first and second barrier metal layers, and the second metal layer only within the damascene opening wherein the first metal layer forms a bottom electrode, the dielectric layer forms a capacitor dielectric, and the second metal layer forms a top electrode to complete fabrication of a crown-type capacitor in the fabrication of an integrated circuit device.

    摘要: A method for making metal-insulator-metal (MIM) capacitors having insulators with high-dielectric-constant and sandwiched between wide-band-gap insulators resulting in low leakage currents and high capacitance per unit area is achieved. The high-k layer increases the capacitance per unit area for next generation mixed-signal devices while the wide-band-gap insulators reduce leakage currents. In a second embodiment, a multilayer of different high-k materials is formed between the wide-band-gap insulators to substantially increase the capacitance per unit area. The layer materials and thicknesses are optimized to reduce the nonlinear capacitance dependence on voltage.

    摘要: A delay-locked loop (DLL) which receives a reference clock signal and outputs an output clock signal is provided. The DLL includes a phase detector, a delay chain, an anti-false lock (AFL) circuit, and a loop filter. The phase detector outputs a first comparison signal according to a phase comparison between the reference clock signal and the output clock signal. The delay chain generates a plurality of strobe clock signals and the output clock signal by delaying the reference clock signal for different intervals. The AFL circuit outputs a second comparison signal according to a phase comparison between the reference clock signal and the strobe clock signals. The loop filter controls the delay time of the output clock signal according to the first and the second comparison signals in order to lock the delay time of the output clock signal at a preset value.
