A capacitive structure and technique for allowing near-instantaneous
charge transport and reliable, wide-band RF ground paths in integrated
circuit devices such as integrated circuit dies, integrated circuit
packages, printed circuit boards, and electronic circuit substrates is
presented. Methods for introducing resistive loss, dielectric loss,
magnetic loss, and/or radiation loss in a signal absorption ring
implemented around a non-absorptive area of one or more conductive layers
of an integrated circuit structure to dampen laterally flowing
Electro-Magnetic (EM) waves between electrically adjacent conductive
layers of the device are also presented.
