MULTI-LAYER INTERCONNECTED SPIRAL CAPACITOR

摘要

An upper planar capacitor is spaced above a lower planar capacitor by a dielectric layer. A bridged-post inter-layer connector couples the capacitances in parallel, through first posts and second posts. The first posts and second posts extend through the dielectric layer, adjacent the upper and lower planar capacitors. A first level coupler extends under the dielectric layer and couples the first posts together and to a conductor of the lower planar capacitor, and couples another conductor of the lower planar capacitor to one of the second posts. A second level coupler extends above the dielectric layer, and couples the second posts together and to a conductor of the upper planar capacitor, and couples another conductor of the upper planar capacitor to one of the first posts.
