The low Er material is used in an area contained by the location of the integrated circuit device and its corresponding decoupling capacitors located nearby. High Er material is used in areas between the regions of low Er material. The low Er material improves that speed at which current from an adjoining decoupling capacitor can propagate to a power pin of the integrated circuit device. The high Er material mitigates cross-coupling of noise between the low Er regions.

    Abstract: Some embodiments include methods of forming capacitors. A metal oxide mixture may be formed over a first capacitor electrode. The metal oxide mixture may have a continuous concentration gradient of a second component relative to a first component. The continuous concentration gradient may correspond to a decreasing concentration of the second component as a distance from the first capacitor electrode increases. The first component may be selected from the group consisting of zirconium oxide, hafnium oxide and mixtures thereof; and the second component may be selected from the group consisting of niobium oxide, titanium oxide, strontium oxide and mixtures thereof. A second capacitor electrode may be formed over the first capacitor electrode. Some embodiments include capacitors that contain at least one metal oxide mixture having a continuous concentration gradient of the above-described second component relative to the above-described first component.

  • Patent number: 7839622
    Abstract: A capacitor device, an electronic circuit comprising a capacitor device, an electronic component, and a method of forming a capacitor device are described. In the capacitor device, a current-path region extends from one of two trench capacitor electrodes to a respective contact structure. The current-path region is obtainable by thinning the substrate from an original substrate thickness down to reduced substrate thickness either in a lateral substrate portion containing the capacitor region or over the complete lateral extension of the substrate before forming the first and second contact structures. The capacitor device exhibits a reduced impedance in the current-path region. This reduced impedance implies a low self-inductance and self-resistance that is caused by the current-path region.

  • Publication number: 20100246092
    Abstract: A thin-film device comprises a base electrode made of a metal, a first dielectric layer, a first inner electrode, a second dielectric layer, a second inner electrode, and a third dielectric layer. Letting T1 be the thickness of the lowermost first dielectric layer in contact with the base electrode in the plurality of dielectric layers, and Tmin be the thickness of the thinnest dielectric layer in the plurality of dielectric layers excluding the first dielectric layer, T1>Tmin. Making the first dielectric layer thicker than the thinnest, dielectric layer in the other dielectric layers can increase the distance between a metal part projecting from a metal surface because of the surface roughness of the base electrode and the inner electrode mounted on the lowermost dielectric layer, thereby reducing leakage currents.
