Abstract:
A method for protecting conductive elements of a semiconductor device package, comprising:providing an assembly including at least one semiconductor die and at least one interposer, said at least one semiconductor die including at least one bond pad on an active surface thereof, said at least one interposer including at least one slot therethrough, said at least one bond pad being exposed through said at least one slot, a first surface of a substrate of said at least one interposer being secured to said active surface by an adhesive layer, said at least one bond pad being connected to a corresponding contact pad of said at least one interposer by way of an intermediate conductive element extending through said at least one slot; forming, without a preformed dam, at least one upwardly protruding dam on a second surface of said substrate at least partially around said at least one slot; and disposing a quantity of encapsulant over said at least one slot and said intermediate conductive element, said at least one upwardly protruding dam at least partially laterally confining said quantity of encapsulant.
