Patent ID: 7898074

Claim:
A packaged electronic device, comprising: a die comprising a substrate including a first substrate surface and an opposing second substrate surface, die circuitry formed on the substrate, and a plurality of electrical contacts located on the first substrate surface and communicating with the die circuitry; a flexible circuit structure bonded directly to the die, the flexible circuit structure comprising: a first structural layer bonded directly to the first substrate surface and having a plurality of first openings respectively aligned with the plurality of electrical contacts; a plurality of electrical conductors, each electrical conductor disposed on the first structural layer and extending through a respective first opening into contact with a respective electrical contact; and a second structural layer disposed on the electrical conductors and having a plurality of second openings defining a respective exposed areas on the electrical conductors, wherein the electrical contacts and the electrical conductors are encapsulated by the first structural layer and the second structural layer; and a barrier film disposed on the die, wherein the electronic device is encapsulated by the barrier film and one or more of the first structural layer and the second structural layer.
