1. A reliable and robust electrical contact comprising:

  • a contact pad and a gate bus patterned from a first metal layer located over a surface of the active die;

    a plurality of dielectric islands formed by patterning a dielectric layer and located over the contact pads, the plurality of dielectric islands being separated from each other by corresponding portions of a second metal layer formed between and over the plurality of dielectric islands;

    a dielectric plate formed by patterning the dielectric layer and positioned over and surrounding the gate bus lines, the dielectric plate being spaced apart from the plurality of dielectric islands by the second metal layer formed between the dielectric plate and the plurality of dielectric islands;

    wherein the contact pad, the plurality of dielectric islands, and the second metal layer provide the reliable and robust electrical contact.
