  • Patent number: 9443922
    Abstract: Techniques and structure are disclosed for providing a MIM capacitor having a generally corrugated profile. The corrugated topography is provisioned using sacrificial, self-organizing materials that effectively create a pattern in response to treatment (heat or other suitable stimulus), which is transferred to a dielectric material in which the MIM capacitor is formed. The self-organizing material may be, for example, a layer of directed self-assembly material that segregates into two alternating phases in response to heat or other stimulus, wherein one of the phases then can be selectively etched with respect to the other phase to provide the desired pattern. In another example case, the self-organizing material is a layer of material that coalesces into isolated islands when heated. As will be appreciated in light of this disclosure, the disclosed techniques can be used, for example, to increase capacitance per unit area, which can be scaled by etching deeper capacitor trenches/holes.

  • Patent number: 9398683
    Abstract: A packaged capacitor component such as a surface mount technology capacitor component may be formed with multiple self-resonant frequencies. The capacitor component may include multiple capacitor portions separated by dielectric layers. The capacitor portions may each be formed from interleaving conductive layers. Additional dielectric layers may be interposed between the interleaving conductive layers. Each capacitor portion may be characterized by a corresponding self-resonance frequency. If desired, a packaged capacitor component having multiple self-resonant frequencies may be formed by stacking multiple surface-mount capacitor components. Each of the stacked surface-mount capacitor components may include interleaving conductive layers that are centered between top and bottom surfaces of that component. Packaged capacitor components having multiple self-resonance frequencies may be used as direct-current blocking capacitors or decoupling capacitors.
