Abstract:
One feature pertains to a multi-chip package that includes a substrate and an electromagnetic interference (EMI) shield coupled to the substrate. At least one integrated circuit is coupled to a first surface of the substrate. The EMI shield includes a metal casing configured to shield the package from radio frequency radiation, a dielectric layer coupled to at least a portion of an inner surface of the metal casing, and a plurality of signal lines. The signal lines are coupled to the dielectric layer and electrically isolated from the metal casing by the dielectric layer. At least one other integrated circuit is coupled to an inner surface of the EMI shield, and at least a portion of the inner surface of the EMI shield faces the first surface of the substrate. The signal lines are configured to provide electrical signals to the second circuit component.
