Described is a method wherein a seal ring is formed by patterning multiple
layers each comprised of a dielectric layer with conductive vias covered by a conductive
layer. Discontinuities are made in the seal ring encapsulating an integrated circuit.
There are no overlaps between different sections of the seal ring thereby reducing
coupling of high frequency circuits in the seal ring structures. In addition, the
distance between signal pads, circuits and the seal ring are enlarged. Electrical
connection is made between deep N-wells and the seal ring. This encapsulates the
integrated circuit substrate and reduces signal coupling with the substrate.
