More Information
Summary:A semiconductor device assembly is provided. The assembly includes a package substrate which has a tunneled interconnect structure. The tunneled interconnect structure has a solder-wettable surface, an interior cavity, and at least one microvia extending from the surface to the cavity. The assembly further includes a semiconductor device disposed over the substrate and a solder joint coupling the device and the substrate. The joint comprises the solder between the semiconductor device and the interconnect structure, which includes the solder on the surface, the solder in the microvia, and the solder within the interior cavity.
