S-SWIFT is a revolutionary new packaging technology

Substrate-SWIFT (S-SWIFT) technology, also known as Silicon Wafer Integrated Fan-Out (on Substrate), is revolutionizing the world of advanced packaging. By boosting I/O and circuit density while shrinking the footprint and profile, S-SWIFT is the go-to solution for both single-die and multi-die applications, perfectly aligning with the escalating demand for higher IC integration in mobile and networking devices.

S-SWIFT stands out as a game-changer in heterogeneous IC packaging, enabling high-performance, cost-effective integration of multiple chiplets and memories. This technology not only increases I/O and circuit density but also paves the way for advanced 3D structures, making it indispensable for the next generation of mobile and networking applications. S-SWIFT technology is well-suited for applications that require large package sizes and high I/O density (>1000).

 

Fan-Out Meets Substrate

An innovative alternative to 2.5D TSV, S-SWIFT is a fan-out package that enhances chip performance and reduces costs. By flip-chip mounting chips onto a high pin count ball grid array (BGA) substrate, and incorporating a re-distribution layer (RDL) for shorter die-to-die (D2D) interconnections, S-SWIFT treats the entire fan-out package as a single die. This intelligent design is then mounted onto the BGA substrate, offering a cost-effective alternative to traditional 2.5D Through Silicon Via (TSV) technology.

A key feature of S-SWIFT is its RDL, which enables shorter D2D interconnections between multiple chips. This design treats the entire fan-out package as a single die, then mounted onto the BGA substrate. By integrating these advanced features, S-SWIFT offers a cost-effective alternative to traditional 2.5D TSV technology.
