1. A semiconductor chip comprising:

  • a silicon substrate;

    multiple active devices in or over said silicon substrate, wherein said active devices comprise a switch controller and a voltage feedback device, wherein said switch controller and said voltage feedback device comprise multiple MOS devices;

    a first dielectric layer over said silicon substrate;

    a metallization structure over said first dielectric layer, wherein said metallization structure is connected to said active devices, and wherein said metallization structure comprises a first metal layer and a second metal layer over said first metal layer;

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

    a passivation layer over said metallization structure and over said first and second dielectric layers, an opening in said passivation layer exposing a pad and a contact pad of said metallization structure; and

    an inductor component and a capacitor component connected to said pads through a first solder layer, wherein said inductor component, said capacitor component, a switch controller and voltage feedback device form a on-chip voltage regulator.
