ABSTRACT:
A capacitor is embedded in a substrate having a small thickness where only a small space for short connection lines is required. The substrate-embedded capacitor includes a substrate having an opening, a first conductive layer on the substrate, a dielectric layer on the first conductive layer, a second conductive layer on the dielectric layer, and an insulating layer formed on the second conductive layer and having an opening. In the substrate-embedded capacitor, the first conductive layer and the second conductive layer are exposed through the openings in the substrate and the insulating layer, respectively.
