Wire bonding method and apparatus for electromagnetic interference shielding
Abstract:
Apparatuses relating generally to a microelectronic package having protection from electromagnetic interference are disclosed. In an apparatus thereof, a platform has an upper surface and a lower surface opposite the upper surface and has a ground plane. A microelectronic device is coupled to the upper surface of the platform. Wire bond wires are coupled to the ground plane with a pitch. The wire bond wires extend away from the upper surface of the platform with upper ends of the wire bond wires extending above an upper surface of the microelectronic device. The wire bond wires are spaced apart from one another to provide a fence-like perimeter to provide an interference shielding cage. A conductive layer is coupled to at least a subset of the upper ends of the wire bond wires for electrical conductivity to provide a conductive shielding layer to cover the interference shielding cage.
