Abstract
Methods for fabricating microelectronic packages, such as Fan-Out Wafer Level Packages, and microelectronic packages are provided. In one embodiment, the method includes placing a first semiconductor die on a temporary substrate, forming an electrically-conducive trace in contact with at least one of the first semiconductor die and the temporary substrate, and encapsulating the first semiconductor die and the electrically-conductive trace within a molded panel. The temporary substrate is removed to reveal a frontside of the molded panel through which the electrically-conducive trace is at least partially exposed. At least one redistribution layer is formed over the frontside of the molded panel, the at least one redistribution layer comprises an interconnect line in ohmic contact with the electrically-conducive trace.
