HPC

The explosion of data from the internet of things (IoT), smartphones, video streaming, and connected technologies is accelerating demand for networking infrastructure — and AI and data analytics demand insatiable computing power from high performance computing (HPC) systems. Meeting that demand with higher performance and better energy efficiency is no longer a chip problem alone; it is a packaging problem. Heterogeneous integration optimizes packaging efficiency along three axes — memory, optics, and power — and ASE offers a comprehensive portfolio to deliver all three.

The Three Integration Axes of HPC Packaging

HPC packaging succeeds or fails on three forms of integration, each addressing a different bottleneck:

  • Memory integration brings high bandwidth memory (HBM) within microns of compute to widen the memory bus and break the bandwidth wall.
  • Optics integration moves the optical engine into the package to raise I/O bandwidth density and lower energy per bit for scale-out.
  • Power integration shortens the power-delivery path to hold efficiency as accelerator currents climb.

Together these deliver the higher bandwidth, better energy efficiency, and lower power consumption that define a competitive HPC system — and they are exactly the axes ASE's VIPack™ platform is built to optimize.

Mapping HPC Requirements to ASE Solutions

To support complex HPC chip designs, ASE offers a packaging portfolio spanning High Performance FCBGA (HFCBGA), 2.5D/3D IC, Fan-Out Chip-on-Substrate (FOCoS and its chip-last FOCoS-CL variant), FOCoS-Bridge, and silicon photonics. The right choice depends on the workload:

HPC need ASE solution What it addresses
CPU packaging HFCBGA High-pin-count compute on an organic substrate
Accelerator + HBM HFCBGA, 2.5D IC, FOCoS-CL, FOCoS-Bridge High-bandwidth, short die-to-die memory interconnect
Memory integration Chiplet integration, HBM memory stacking Maximum bandwidth density to feed compute
More-than-Moore compute Chiplet integration Partitioned dies on optimal process nodes
Networking High-speed HFCBGA, electrical + optical integration, silicon photonics High-throughput switch/router and optical I/O

For an HPC architect, this portfolio means the interconnect density — and therefore the cost — can be matched to each block of the system: FOCoS-Bridge or 2.5D where die-to-die bandwidth is paramount, FOCoS where 2μm/2μm fan-out routing suffices, and silicon photonics where the link leaves the package.

Why a Single Portfolio Matters at the System Level

HPC silicon rarely needs just one technology. A single accelerator may pair an HFCBGA host with FOCoS-Bridge-integrated HBM and co-packaged optics for scale-out. Sourcing these from one outsourced semiconductor assembly and test (OSAT) provider lets architects co-optimize across them rather than re-qualifying across vendors — and ASE's Integrated Design Ecosystem™ (IDE) supports that chip-package-system co-design across signal integrity, thermal behavior, and power delivery. With the advanced packaging market projected by Yole Group to grow from about US$46 billion in 2024 to more than US$79.4 billion by 2030 — led by AI and HPC — that breadth is a strategic advantage, not just a convenience.

Conclusion

HPC performance is now engineered in the package, across memory, optics, and power integration. With HFCBGA, FOCoS, FOCoS-Bridge, 2.5D/3D IC, and silicon photonics unified under the VIPack™ platform and the IDE co-design environment, ASE — the world's largest OSAT — gives HPC customers a single portfolio to match interconnect density to cost across every block of the system, from CPU to accelerator to optical networking.

Frequently Asked Questions

Q: What packaging technologies does ASE offer for HPC? A: ASE offers a comprehensive HPC portfolio including High Performance FCBGA (HFCBGA), 2.5D/3D IC, Fan-Out Chip-on-Substrate (FOCoS and FOCoS-CL), FOCoS-Bridge, and silicon photonics — all within the VIPack™ platform.

Q: What are the three integration axes for HPC packaging? A: Memory integration (HBM close to compute for bandwidth), optics integration (in-package optical engines for energy-efficient scale-out), and power integration (shorter power-delivery paths for efficiency). Together they deliver higher bandwidth, better energy efficiency, and lower power consumption.

Q: Which ASE technology is best for accelerator-plus-HBM integration? A: FOCoS-CL and 2.5D IC integrate an accelerator with HBM through fine die-to-die routing, while FOCoS-Bridge delivers the highest die-to-die density where a specific link needs it — chosen by required bandwidth and cost target.

Q: How does optics integration help HPC? A: Bringing silicon photonics and co-packaged optics into the package raises I/O bandwidth density and lowers energy per bit, which is decisive for networking and scale-out as electrical I/O becomes power-limited.

Q: Why source HPC packaging from one OSAT? A: HPC silicon often combines HFCBGA, FOCoS-Bridge, and optics in one system. Sourcing from one provider lets architects co-optimize across technologies with the Integrated Design Ecosystem™ (IDE) instead of re-qualifying across vendors.
