    Abstract: A lead frame (52, 100, 112) for a semiconductor device (die) package (50, 102, 110) is described. Each of the leads (60) in the lead frame (52, 100, 112) includes an interposer (64) having one end (66) disposed proximate the outer face (58) of the package (50, 102, 110) and another end (68) disposed proximate the die (14). Extending from opposite ends of the interposer (64) are a board connecting post (70) and a support post (74). A bond site (78) is formed on a surface of the interposer (64) opposite the support post (74). Each of the leads (60) is electrically connected to an associated input/output (I/O) pad (80) on the die (14) via wirebonding, tape bonding, or flip-chip attachment to the bond site (78). Where wirebonding is used, a wire electrically connecting the I/O pad (80) to the bond site (78) may be wedge bonded to both the I/O pad (80) and the bond site (78). The support post (74) provides support to the end (68) of the interposer (64) during the bonding and coating processes.
