1. A semiconductor chip comprising:

  • a semiconductor substrate;

    multiple active devices in said semiconductor substrate;

    a first dielectric layer coupled to said semiconductor substrate;

    a conductive structure coupled to said first dielectric layer and said semiconductor substrate, wherein said conductive structure comprises a first conductive layer and a second conductive layer coupled to said first conductive layer, wherein said first conductive layer and said second conductive layer comprise an inductor within the semiconductor chip;

    a second dielectric layer between said first and second conductive layers;

    a passivation layer coupled to said first and second conductive layers and said first and second dielectric layers, wherein said passivation layer comprises a nitride;

    a discrete capacitor coupled to said passivation layer; and

    a solder between said discrete capacitor and a contact point of said conductive structure.
