Patent ID: 8901710

Claim:
A capacitor comprising: a first dielectric layer comprising a first dielectric material, said first dielectric layer having a top surface and a first thickness, and said first dielectric layer further having a first coefficient of capacitance with respect to a specific parameter; first metal wires and second metal wires in said first dielectric layer at said top surface, said first metal wires being interdigitated with said second metal wires, being physical separated from said second metal wires by spaces, and further being electrically isolated from said second metal wires by said first dielectric material in said spaces; and a second dielectric layer on said top surface and extending laterally over said first metal wires and said second metal wires, said second dielectric layer comprising a second dielectric material different from said first dielectric material and having a second thickness that is different from said first thickness, and said second dielectric layer further having a second coefficient of capacitance with respect to said specific parameter, said first coefficient of capacitance and said second coefficient of capacitance having opposite polarities, said spaces physically separating said first metal wires from said second metal wires being a predetermined length, and said first thickness to said second thickness being a predetermined ratio such that said capacitor has a specific net coefficient of capacitance of approximately zero with respect to said specific parameter.
