Technical content

Amkor’s popular Package Stackable Very Thin Fine Pitch BGA (PSvfBGA) platform supports single die, stacked die using wirebond or hybrid (FC plus wirebond) stacks and has been applied to Flip Chip (FC) applications to improve warpage control and package integrity through test and SMT handling. As handheld microprocessors have transitioned to advanced CMOS nodes with higher speed cores with higher I/O, there has been a transition from wirebond to flip chip die designs. Flip chip enables the use of an exposed die bottom package that integrates the package stacking design features of PSvfBGA in a fcCSP assembly flow, which Amkor calls Package Stackable Flip Chip Chip Scale Package (PSfcCSP). PSfcCSP has a thin exposed FC die enabling fine pitch stacked interfaces at 0.5 mm pitch which is a challenge in a center molded PSvfBGA structure. Continued development resulted in Amkor entering the second generation of PoP applications where new memory architectures, required in mobile multimedia applications, demand higher density stacked interfaces in combination with PoP mounted area and height reductions. The previous PSvfBGA and PSfcCSP structures limited the ability of the memory interface to scale in density and pitch, resulting in the need for a new bottom PoP structure. Amkor developed new technologies to create the next-generation PoP solution with interconnect vias through the mold cap. Known as Through Mold Via (TMV®), this technology provides a stable bottom package that enables use of thinner substrates with a larger die to package ratio. TMV ® enabled PoP can support single, stacked die or FC designs. TMV ® is an ideal solution for the emerging 0.4 mm pitch low power DDR2 memory interface requirements and enables the stacked interface to scale with solder ball pitch densities to 0.3 mm pitch or below. The next few years promise to provide many new challenges and applications for PoP, as handheld multimedia applications continue to demand higher signal processing power and data storage capabilities. Amkor is committed to maintaining strong development and production capabilities to ensure we are at the forefront in meeting next-generation PoP requirements.

Applications

PoP packages are designed for products requiring efficient memory architectures including multiple buses and increased memory density and performance, while reducing mounted area. Portable electronic products such as mobile phones (baseband or applications processor plus combo memory), digital cameras (image processor plus memory), portable media players (audio/graphics processor plus memory), gaming and other mobile applications can benefit from the combination of stacked package and small footprint offered by Amkor’s PoP family.
