Abstract

A packaged electronic device includes a flexible circuit structure and a die. The flexible circuit structure includes a first structural layer and electrical conductors. The die is bonded to the flexible circuit structure by a flexible attachment layer. The die includes interconnects in electrical contact with die circuitry and extending through the die, through the flexible attachment layer, and into electrical contact with respective electrical conductors at first ends. A flexible second structural layer is disposed on the die and exposed portions of the electrical conductors, wherein the die and the electrical conductors are encapsulated by the first structural layer and the second structural layer. The first structural layer and/or the second structural layer include a plurality of openings defining respective exposed areas on the electrical conductors at second ends.
