ABSTRACT:
A leadframe (100) has a flag having an outer contour that tapers from first and second opposing ends (160, 162) to a common point, the midline (200) of the flag. The tapering of the leadframe is continuous, extending from points adjacent the first and second ends or from the ends themselves, to the common midline. According to this structure, a wide range of die sizes may be accommodated with a single leadframe, while simultaneously preventing popcorning of the packaged semiconductor device (300) incorporating the leadframe.
