Abstract

A structure and method to improve saw singulation quality and wettability of integrated circuit packages (140) assembled with lead frames (112) having half-etched recesses (134) in leads. A method of forming a semiconductor device package includes providing a lead frame strip (110) having a plurality of lead frames. Each of the lead frames includes a depression (130) that is at least partially filled with a material (400) prior to singulating the strip.
