Abstract
A capacitor-embedded substrate for reliably compensating for fluctuation of a power source voltage is provided. A decoupling capacitor is formed between an input side electrode layer and an output side electrode layer via interlayer insulating layers, the decoupling capacitor includes a ground layer, a power source layer, and a dielectric layer interposed therebetween. A plurality of power supply terminals used for power supply to a semiconductor device is formed by patterning the output side electrode layer and is connected to the power source layer via a capacitor via.
