A microelectronic package includes at least one microelectronic element having a front surface defining a plane, the plane of each microelectronic element parallel to the plane of any other microelectronic element. An encapsulation region overlying edge surfaces of each microelectronic element has first and second major surfaces substantially parallel to the plane of each microelectronic element and peripheral surfaces between the major surfaces. Wire bonds are electrically coupled with one or more first package contacts at the first major surface of the encapsulation region, each wire bond having a portion contacted and surrounded by the encapsulation region. Second package contacts at an interconnect surface being one or more of the second major surface and the peripheral surfaces include portions of the wire bonds at such surface, and/or electrically conductive structure electrically coupled with the wire bonds.

Apparatuses relating generally to a microelectronic package having protection from interference are disclosed. In an apparatus thereof, a substrate has an upper surface and a lower surface opposite the upper surface and has a ground plane. A first microelectronic device is coupled to the upper surface of the substrate. Wire bond wires are coupled to the ground plane for conducting the interference thereto and extending away from the upper surface of the substrate. A first portion of the wire bond wires is positioned to provide a shielding region for the first microelectronic device with respect to the interference. A second portion of the wire bond wires is not positioned to provide the shielding region. A second microelectronic device is coupled to the substrate and located outside of the shielding region. A conductive surface is over the first portion of the wire bond wires for covering the shielding region.

A microelectronic package includes at least two semiconductor die, one die stacked over at least partially another. At a least the upper die is oriented with its active surface facing in the direction of a redistribution structure, and one or more wires are coupled to extend from contacts on that active surface into conductive structures in the redistribution structure.
