ABSTRACT:
A ball grid array capacitor has a substrate with a top and bottom surface and a via extending through the substrate. Several capacitors are located on the bottom surface. The capacitors include a top electrode connected to the via, a dielectric layer connected to the top electrode, and a bottom electrode that is connected to the dielectric layer and a ball pad over the bottom electrode. A passivation layer is located between the capacitors. Several solder spheres are electrically and mechanically connected to the bottom electrode. A resistor can be mounted on the top surface and connected to the via to form a filter.
