A stacked die semiconductor package that includes a substrate with a
plurality of adhesive portions arranged in a manner to create at least
one gap between the adhesive portions. The package also includes a first
semiconductor chip having a non-active surface in contact with the
adhesive portions, and an active surface being electrically connected to
the substrate. In the package, a second semiconductor chip the non-active
surface of the second semiconductor chip is attached to the non-active
surface of the first semiconductor chip by a layer of adhesive
therebetween. The active surface of the second semiconductor chip is
electrically connected to the substrate. An encapsulant material covers
the first and second semiconductor chips and their associated electrical
connections. The encapsulating material fills the at least one gap
between the plurality of adhesive portions and thereby encapsulates the
second semiconductor chip and its associated electrical connection.
