Abstract
Circuits for shielding devices from electromagnetic coupling with through-silicon vias are shown that include a substrate having a through via, which provides access to a device layer on a first surface of the circuit to a device layer on a second surface of the circuit; a conductive layer on the first side of the substrate; a contact point on one of the device layers; and a grounded buried interface tie on the conductive layer, adjacent to the contact point, to isolate the contact point from coupling noise.
