Abstract:
1. A method for making a microelectronic unit, comprising the steps of: forming a plurality of wire bonds on a first surface that is a conductive bonding surface of a structure comprising a patternable metallic element, the wire bonds having bases joined to the first surface and end surfaces remote from the bases and remote from the first surface, the wire bonds further having edge surfaces extending between the bases and the end surfaces; forming a dielectric encapsulation layer over at least a portion of the first surface of the conductive layer and over portions of the wire bonds, such that unencapsulated portions of the wire bonds are defined by at least one of the end surface or a portion of the edge surface thereof that is uncovered by the encapsulation layer; and then patterning the metallic element selectively to form first conductive elements insulated from one another by at least portions of the encapsulation layer, wherein at least some of the wire bonds are disposed atop the first conductive elements.
