    Abstract: A semiconductor device is disclosed mounted at an angle on a signal carrier medium such as a printed circuit board. The semiconductor device includes a stack of semiconductor die stacked in a stepped offset configuration. The die stack may then be encapsulated in a block of molding compound.
