Patent ID: 7749809

Claim:
A method of constructing a panel suitable for use in the packaging of integrated circuit dice, comprising: providing a substrate formed from a sacrificial semiconductor wafer, the substrate having a first surface including a plurality of device areas; metallizing the first surface of the substrate to form an array of metallized electrically isolated contacts that are not electrically connected to any circuits within the wafer, each of the array of contacts having a first surface; encapsulating the first surface of the substrate and the array of contacts with molding material while leaving first surfaces of the contacts substantially exposed and uncovered by molding material; after the encapsulating, metallizing the substrate to form a plurality of traces over the molding material and the contacts, each of the plurality of traces including a trace portion and an associated bonding portion, the associated bonding portion not being positioned on the first surface of any of the contacts, the trace portion being formed on the first surface of an associated contact and extending over the molding material and beyond the associated contact to physically and electrically connect the first surface of the associated contact to the associated bonding portion.
