Abstract: A new flip-chip technology, denominated as DDFC (Direct-Downset Flip-Chip) technology, is characterized by the forming of a downset device hole in the substrate, and by the use of an array of solder bumps over the semiconductor chip and an array of recessed solder-bump pads of an inwardly-tapered conical shape over the bottom surface of the device hole for bonding the semiconductor chip to the substrate. During assembly, the semiconductor chip is embedded in a direct-downset manner into the device hole of the substrate, with the solder bumps being fitted and wetted to the recessed solder-bump pads. The proposed DDFC technology can be implemented without requiring solder-deflux or flip-chip underfill processes, thereby simplifying overall package fabrication.
