Abstract:
A semiconductor device has an electrical component and an e-bar structure disposed to a side of the electrical component. An encapsulant is deposited over the electrical component and e-bar structure. An RDL is formed over the electrical component, encapsulant, and e-bar structure. The e-bar structure has a core layer, a first conductive layer formed over a first surface of the core layer, and a second conductive layer formed over a second surface of the core layer. The second conductive layer includes a thickness greater than the first conductive layer. The RDL has an insulating layer formed over the electrical component and encapsulant, and a conductive layer formed over the insulating layer. A bump is formed over a contact pad of the e-bar structure opposite the RDL. A contact pad of the electrical component is electrically connected to the RDL opposite the bump.
