Abstract:
1. A method for producing an electronic component, the method comprising: applying a plurality of spaced metallization layers at predetermined anchoring locations along a surface of a sacrificial substrate such that the sacrificial substrate surface defines metalized areas and non-metalized areas, wherein the surface including the metallization layers defines a top side of the sacrificial substrate, and wherein the sacrificial substrate comprises paper; anchoring an integrated circuit element to each of said metallization layers disposed on the top side of the sacrificial substrate, each integrated circuit element including a bonding pad; forming contact-connecting points on the top side of the sacrificial substrate by placing an arrangement of bonding bumps on the sacrificial substrate such that a portion of each bonding bump is in direct contact with the sacrificial substrate; performing wire bonding between the bonding bumps on the sacrificial substrate and the bonding pad of the integrated circuit element to electrically connect the integrated circuit element to the sacrificial substrate; covering the top side of the sacrificial substrate with a mold including internal shaping configured to define a breaking point between adjacent integrated circuit elements, the breaking point configured to facilitate singulation; filling the mold with molding compound to encapsulate the integrated circuit element anchored and contact-connected to the sacrificial substrate, as well as to encapsulate the bonding bump portion not in direct contact with the sacrificial substrate, wherein the mold forms a continuous molding compound layer including a plurality of defined breaking points; removing the sacrificial substrate to uncover one or more of the contact-connecting points disposed within the encapsulation by exposing the portion of the bonding bump in direct contact with the substrate; and singulating, after the removal of the sacrificial substrate, the continuous molding compound layer into individual components by cutting along one or more of the breaking points to produce at least one electronic component.
