The formation is arranged so that adjacent die areas are separated by a path for a dicing tool. Within each path, a pair of spaced apart lines is fabricated. Each line defines a dicing edge of a respective path and has at least one trench extending between a top surface of the wafer and the substrate. Each trench is filled with a stress absorbing material for reducing die tool induced stress on the die areas during dicing.

A carrier is attached to the first surface of the flexible tape. Then conductive pillars are formed on the second set of bond pads and an intermediate layer of polymeric compound is deposited on the second surface of the flexible tape. After the compound has cured, a surface of the intermediate layer is ground to expose ends of the conductive pillars to form a sub-assembly comprising the flexible tape and the intermediate layer. Then the carrier is removed from the sub-assembly, thereby creating an interposer. The interposer is attached to a substrate and at least one die is attached to the interposer.
