Patent ID: 8169014

Claim:
A capacitor structure for an integrated circuit, comprising: a first layer of substantially parallel interdigitated first strips, adjacent first strips alternating between a first polarity and an opposite second polarity; a first capacitor dielectric layer of strips disposed over and in alignment with the interdigitated strips of the first layer; a first extension layer of substantially parallel interdigitated first extension strips disposed over the strips of the first capacitor dielectric layer and each having a length, adjacent ones of the first extension strips alternating between the first polarity and the second polarity, each first extension strip being disposed over the first capacitor dielectric strip that is disposed over a first strip of the opposite polarity; and a first sequence of first vias coupled to and arranged along the lengths of the first extension strips of the first extension layer, adjacent ones of the first vias alternating between the first polarity and the second polarity, each first via being disposed over a first extension strip of the same polarity.
