A package that includes a substrate, an integrated device coupled to the substrate, and an integrated passive device comprising at least two capacitors. The integrated passive device is coupled to the substrate. The integrated passive device includes a passive device substrate comprising a first trench and a second trench, an oxide layer located over the first trench and the second trench, a first electrically conductive layer located over the oxide layer the first trench, a dielectric layer located over the first electrically conductive layer, and a second electrically conductive layer located over the dielectric layer.
