11133241 · 2021-09-28 · ·

A semiconductor package having an aperture in a die pad and solder in the aperture coplanar with a surface of the package is disclosed. The package includes a die pad, a plurality of leads, and a semiconductor die coupled to the die pad with a die attach material. A cavity or aperture is formed through the die pad to expose a portion of the die attach material. Multiple solder reflows are performed to reduce the presence of voids in the die attach material. In a first solder reflow, the voids of trapped gas that form when attaching the die to the die pad are released. Then, in a second solder reflow, solder is added to the aperture coplanar with a surface of the die pad. The additional solder can be the same material as the die attach material or a different material.
