VIPack™
AI workloads now demand levels of performance, bandwidth, and energy efficiency that transistor scaling alone can no longer deliver. As the economics of shrinking a single monolithic die break down, the gains have to come from somewhere else — from integrating multiple optimized dies into one high-performance system. That shift turns advanced packaging from a back-end process into a strategic enabler of system innovation, and it is the premise behind ASE's VIPack™: a vertically integrated advanced packaging platform engineered for the most demanding AI, high-performance computing (HPC), and data-center requirements.
What Makes VIPack™ a Platform, Not a Product List
VIPack™ combines three things that a catalog of individual package types cannot: ultra-high-density interconnect, heterogeneous integration (HI) across dies of different process nodes and functions, and a co-design ecosystem that spans silicon, package, and system. The point of integrating them is to let customers move from architecture to production faster — choosing the right interconnect approach for a given die mix, then verifying it across domains before committing to silicon. The platform delivers the fine-pitch horizontal and vertical interconnects needed to tightly couple disaggregated systems-on-chip (SoCs) with high bandwidth memory (HBM) and accelerators, which is exactly what large-scale AI training and inference workloads require.
The Six VIPack™ Technology Pillars
VIPack™ is built on six core packaging technology pillars, supported by a comprehensive co-design ecosystem. Rather than competing, they cover a spectrum of integration needs — from ultra-thin mobile modules to reticle-busting AI accelerators.
| Pillar | What it provides | Where it leads |
|---|---|---|
| Fan-Out Package-on-Package (FOPoP) | 3D stacking in an ultra-low profile | Application processors, AR/VR, CPO |
| Fan-Out Chip-on-Substrate (FOCoS) | RDL-based chiplet integration, line width/line spacing (L/S) as fine as 2μm/2μm | Logic + HBM without a silicon interposer |
| Fan-Out Chip-on-Substrate-Bridge (FOCoS-Bridge) | Embedded silicon bridge for interposer-grade die-to-die routing | Multi-die ASIC + HBM, highest D2D density |
| Fan-Out System-in-Package (FOSiP) | System-level fan-out integration of dies and passives | Integrated modules, RF/analog content |
| 2.5D/3D IC | TSV-based silicon interposer and stacking, L/S down to 0.5μm/0.5μm | Maximum interconnect density |
| Co-Packaged Optics (CPO) | Optical I/O integrated into the package | AI networking, lower energy per bit |
The fan-out family (FOPoP, FOCoS, FOCoS-Bridge, FOSiP) builds interconnect on a reconstituted wafer using a redistribution layer (RDL), avoiding a silicon interposer where one is not needed; the through silicon via (TSV)-based 2.5D/3D IC pillar adds the interposer and vertical stacking where maximum density justifies the cost; and CPO extends the platform into the optical domain. A designer does not pick VIPack™ — they pick the pillar that matches their die mix, with the rest of the platform available as the design evolves.
Fine-Pitch Interconnect for HBM and Disaggregated SoCs
The common thread across the pillars is interconnect that is fine enough and short enough to move data the way AI silicon needs. VIPack™ enables both high-density horizontal interconnect — for placing HBM stacks beside a compute die — and vertical interconnect for stacking. Tightly coupling disaggregated SoCs with HBM through 2μm/2μm RDL or sub-micron interposer routing directly addresses the memory-bandwidth wall that throttles AI throughput, while co-design of signal integrity, thermal performance, and power delivery preserves the margins those high data rates consume. For the customer, the payoff is twofold: the bandwidth and power integrity to feed a large accelerator, and a shorter path to deployment because the package was optimized alongside the silicon rather than after it.
VIPack™ for AI Infrastructure, Edge, and Mobile
The platform stretches across the full range of AI form factors. For AI infrastructure, VIPack™ supports advanced networking and co-packaged optics integration, raising I/O bandwidth density and lowering energy per bit — both key enablers for next-generation AI clusters and data centers where interconnect power is a first-order constraint. At the other end of the spectrum, VIPack™ extends to edge and mobile AI with ultra-thin system-in-package solutions that integrate RF, analog, and passive components within RDL layers, meeting the aggressive form-factor, thermal, and power limits of devices that run on a battery. The same platform philosophy — integrate what the application needs, at the density it justifies — applies whether the target is a 700W data-center accelerator or a wearable inference module.
Co-Design Across Silicon, Package, and System
A platform this broad only delivers if customers can navigate it, which is why VIPack™ is paired with ASE's Integrated Design Ecosystem™ (IDE). Co-design across the silicon, package, and system domains lets engineers optimize signal integrity, thermal performance, and power delivery together rather than in sequence — and reduces the design iteration cycles that otherwise extend time to deployment. For a customer evaluating a complex multi-die package, that co-design layer is what converts a set of advanced technologies into a predictable, manufacturable result.
Scalable by Design
VIPack™ is built to track evolving process nodes and architectural roadmaps, so a design choice made today aligns with the platform's direction tomorrow. That scalability is the practical reason to standardize on a platform rather than a point solution: as an accelerator's die count, HBM stack count, or bandwidth target grows across generations, the customer can move up the VIPack™ pillars — from fan-out to bridge to full 2.5D/3D, and into CPO — without changing packaging partners or re-learning a new design flow.
Conclusion
Advanced packaging has become the layer where AI system performance is won, and VIPack™ is ASE's answer to that shift: six interconnect pillars spanning fan-out, TSV-based 2.5D/3D IC, and co-packaged optics, unified by heterogeneous integration and a co-design ecosystem. By matching the right interconnect density to each design and verifying it across silicon, package, and system, VIPack™ helps customers accelerate from architecture to production. As the world's largest outsourced semiconductor assembly and test (OSAT) provider, ASE delivers the platform with the manufacturing scale to carry a design from first prototype to high volume.

Frequently Asked Questions
Q: What is ASE's VIPack™ platform? A: VIPack™ is ASE's vertically integrated advanced packaging platform, engineered for AI, high-performance computing (HPC), and data-center applications. It combines ultra-high-density interconnect, heterogeneous integration (HI) across dies of different nodes and functions, and a co-design ecosystem, and it is built on six core packaging technology pillars supported by ASE's Integrated Design Ecosystem™ (IDE).
Q: What are the six VIPack™ technology pillars? A: The six pillars are Fan-Out Package-on-Package (FOPoP), Fan-Out Chip-on-Substrate (FOCoS), Fan-Out Chip-on-Substrate-Bridge (FOCoS-Bridge), Fan-Out System-in-Package (FOSiP), TSV-based 2.5D/3D IC, and Co-Packaged Optics (CPO). Together they span a spectrum from ultra-thin mobile modules to high-density AI accelerators and optical I/O integration.
Q: How does VIPack™ support AI and HPC workloads? A: VIPack™ provides fine-pitch horizontal and vertical interconnects — such as FOCoS at 2μm/2μm L/S and 2.5D/3D IC down to 0.5μm/0.5μm — that tightly couple disaggregated SoCs with high bandwidth memory (HBM) and accelerators. This addresses the memory-bandwidth wall, supports low-latency communication, and, through co-packaged optics, raises I/O bandwidth density while lowering energy per bit.
Q: What is the difference between the fan-out and 2.5D/3D pillars of VIPack™? A: The fan-out pillars (FOPoP, FOCoS, FOCoS-Bridge, FOSiP) build interconnect on a reconstituted wafer with a redistribution layer (RDL), avoiding a silicon interposer where it is not needed. The 2.5D/3D IC pillar uses a through silicon via (TSV)-based silicon interposer and vertical stacking for maximum interconnect density, applied where that density justifies the added cost.
Q: How does the Integrated Design Ecosystem™ (IDE) work with VIPack™? A: IDE is the co-design layer that lets customers optimize signal integrity, thermal performance, and power delivery across the silicon, package, and system domains simultaneously. By verifying a VIPack™ package design across these domains before committing to silicon, IDE reduces design iteration cycles and shortens overall time to deployment.
