A die attach region for use in an IC package is described. The die attach
region employs a number of posts interconnected with a number of support
risers to provide a structure that upholds a semiconductor die while
facilitating flow of an encapsulant material underneath the die during
encapsulation. The posts and risers can be arranged in a number of
configurations that each facilitate flow of encapsulant material. This
die attach region can be incorporated into a lead-frame structure or a
substrate panel for ease and efficiency of manufacture.
