Abstract:
Some implementations provide a substrate that includes several traces, a solder resist layer covering the several traces, and a testing pad coupled to a trace from the several traces. The testing pad is at least partially exposed and at least partially free of the solder resist layer when a chip is coupled to the substrate. In some implementations, the several traces have a pitch that is 100 microns (μm) or less. In some implementations, the substrate is a package substrate. In some implementations, the package substrate is a package substrate on which a thermal compression flip chip is mounted during an assembly process. In some implementations, the testing pad is free of a direct connection with a bonding component of the chip when the chip is coupled to the substrate. In some implementations, the bonding component is one of a solder ball.

The barrier layer includes a top portion, a bottom portion and a side portion. The top portion is coupled to the UBM structure, and the side portion is substantially oxidized.

Abstract:
A backside mold configuration (BSMC) process for manufacturing packaged integrated circuits includes applying a mold compound to a side of a packaging substrate opposite an attached die. The mold compound is deposited on a dielectric (such as photo resist). The mold compound and dielectric are patterned after coupling a die to the packaging substrate to expose a contact pad of the packaging substrate. After patterning the mold compound and dielectric, a packaging connection is coupled to contact pads through the mold compound and dielectric. The mold compound surrounding the packaging connection reduces warpage of the packaging substrate during processing. Additionally, patterning the dielectric after attaching the die improves reliability of the packaging connection.
