Abstract

An integrated circuit package (60) has a substrate (12) with a first surface (51) for mounting a semiconductor die (20) and a second surface (52) defining a via (70). A lead (26) is formed by plating a conductive material to project outwardly from the second surface. The conductive material extends from the lead through the first via for coupling to the semiconductor die.
