ABSTRACT:
A system within a circuit is disclosed. The system comprises a first shield and a device above the first shield. The system also includes a plurality of conductive walls coupled to and extending from the first shield to block electromagnetic (EM) waves to other parts of the circuit. A system and method in accordance with the present invention adds metal walls on the edge of a sliced shield. The walls block the electromagnetic wave from coupling to other parts of the circuit from a sideways direction.
