Patent ID: 8173490

Claim:
A method for fabricating a packaged electronic device, the method comprising: fabricating a flexible circuit structure on a first substrate surface of a substrate by: depositing a first structural layer on the first substrate surface wherein the first structural layer is bonded directly to the first substrate surface; forming a plurality of electrical conductors on the first structural layer and in signal communication with die circuitry of the substrate; and depositing a second structural layer on the electrical conductors, wherein the electrical conductors are encapsulated by the first structural layer and the second structural layer, and the flexible circuit structure in combination with the substrate forms an electronic device; and depositing a barrier film on a second substrate surface of the substrate opposite to the first substrate surface, and on an outer lateral surface of the substrate extending generally between the first substrate surface and the second substrate surface, wherein the electronic device is encapsulated by the barrier film and one or more of the first structural layer and the second structural layer.
