2024 Council Meeting Keynote — IC Package Substrates for Heterogenous Integration: Future Challenges and Opportunities



Advanced packaging is enabling unprecedented levels of product performance as logic and memory chiplets are heterogeneously integrated in unique architectures, merging back-end silicon fabrication with package assembly. IC package substrates are a crucial component of future advanced packaging technologies to enable efficient power delivery, high-speed I/O signalling and dense, low latency die-to-die interconnections. To meet future challenges, IC substrates are evolving from fiberglass reinforced epoxy (organic) core substrates to glass core substrates. Glass has unique physical and optical properties that allow for more transistors to be delivered in a package, providing better scaling and enabling the assembly of larger chiplet complexes. In this talk, Dr. Manepalli will discuss an overview of state-of-the-art IC package substrate technologies, and future challenges and opportunities in scaling IC package substrates.
