Abstract: electronic devices that include a routing substrate with lower inductance path for a capacitor, and related fabrication methods. in exemplary aspects, to provide lower interconnect inductance for a capacitor coupled to a power distribution network in the routing substrate, an additional metal layer that provides an additional, second power plane is disposed in a dielectric layer between adjacent metal layers in adjacent metallization layers. the additional, second power plane is adjacent to a first power plane disposed in a first metal layer of one of the adjacent metallization layers. the disposing of the additional metal layer in the dielectric layer of the metallization layer reduces the thickness of the dielectric material between the first and second power planes coupled to the capacitor as part of the power distribution network. this reduced dielectric thickness between first and second power planes coupled to the capacitor reduces the interconnect inductance for the capacitor.
