Abstract
An apparatus includes a substrate, a switching device, a capacitor device, a first via, a second via, a third via and a fourth via. The substrate has a first surface and a second surface and includes a plurality of copper layers including M positive copper layers and N negative copper layers. The M positive copper layers and the N negative copper layers are alternated. The switching device is disposed on the first surface and includes a switching positive terminal and a switching negative terminal. The capacitor device is disposed on the first surface and includes a capacitor positive terminal and a capacitor negative terminal, and the capacitor device forms a capacitor area. The projections of the adjacent positive and negative copper layers and the capacitor area on the first surface at least partially overlap with each other.
