Abstract:
1. A panel suitable for use in the packaging of integrated circuit dice, the panel comprising: a substrate formed from a sacrificial semiconductor wafer, the substrate having a first surface including a plurality of device areas; a multiplicity of metallized electrically isolated contacts that are not electrically connected to any circuits within the wafer, the contacts being arranged such that each device area includes an array of the contacts, each contact having a first portion and a second portion, each first portion of a contact being in contact with the first surface of the substrate, each second portion of a contact being positioned over the first surface of an associated first portion of a contact and physically and electrically connected with the associated first portion of the contact, wherein the second portions of selected ones of the contacts each include an associated bonding portion that is not positioned directly over the first portion of the contact and an associated trace portion that electrically connects the bonding portion with the portion of the contact directly over the associated first portion of the contact; and a molding material that encapsulates portions of the first surface of the wafer, the first portions of the contacts and the second portions of the contacts while leaving outer surfaces of the second portions of the contacts including outer surfaces of the bonding portions exposed.
