Abstract:
1. A passive device structure comprising a capacitor, the capacitor comprising: a first electrode; a second electrode; and a dielectric structure comprising a conductive layer and a dielectric layer between the first electrode and the second electrode, the dielectric layer comprising a metal oxide selected from the group consisting of aluminum oxide, niobium oxide, titanium oxide, tungstic oxide, zirconium oxide, and tantalum oxide, wherein the dielectric structure has a first width greater than a second width of the second electrode, the passive device structure further comprising a resistor, the resistor comprising: a first contact; a second contact, wherein the first electrode, the first contact, and the second contact are portions of a first metal layer; a resistive structure electrically connected to the first contact and the second contact, the resistive structure comprising: a conductive layer; and a dielectric layer comprising a metal oxide selected from the group consisting of aluminum oxide, niobium oxide, titanium oxide, tungstic oxide, zirconium oxide, and tantalum oxide.
