It’s official: semiconductors are cool—and more importantly, they are mission-critical. They power the AI models reshaping industries, the data centers scaling global intelligence, and the high-performance systems driving breakthroughs across healthcare, science, and digital infrastructure. Today, semiconductors form the backbone of modern society, delivering the functionality, performance, and energy efficiency required to deliver extraordinary value at scale.
Nowhere is this more evident than in AI and data centers. The exponential growth in model complexity, training workloads, and inference demand is redefining what compute platforms must deliver. Semiconductor innovation is enabling this transformation by powering hyperscale data centers, advancing high-performance computing, accelerating networking bandwidth, and enabling intelligent systems across every sector.
Historically, semiconductor innovation focused on optimizing individual chips for specific functions. That approach is no longer sufficient. Today’s AI and data center architectures require system-level integration by combining logic, memory, and connectivity to deliver performance, bandwidth, and power efficiency at scale. This shift has placed advanced packaging at the center of semiconductor innovation.
Advanced packaging enables the integration of multiple chips—or chiplets—into a single, high-density package, creating tighter integration, higher bandwidth, and improved power delivery. It has become a critical enabler for AI accelerators, high-bandwidth memory architectures, and next-generation data-center platforms where traditional scaling approaches are reaching their limits.
At ASE, we anticipated this shift. As the world’s leading OSAT, ASE introduced VIPack™ to provide customers with a flexible and comprehensive portfolio of advanced packaging solutions tailored to the most demanding applications. VIPack™ is a vertically integrated packaging platform designed to enable next-generation system architectures for AI, HPC, and data-center infrastructure.
The name VIPack™ reflects both form and function. “VI” stands for Vertically Integrated and also represents the Roman numeral six—a reference to the platform’s six core packaging technology pillars. These pillars are supported by a fully integrated co-design ecosystem that accelerates innovation from architecture definition through high-volume manufacturing.
VIPack™ includes ASE’s high-density RDL-based Fan-Out Package-on-Package (FOPoP), Fan-Out Chip-on-Substrate (FOCoS), Fan-Out Chip-on-Substrate-Bridge (FOCoS-Bridge), and Fan-Out System-in-Package (FOSiP), as well as TSV-based 2.5D and 3D IC and co-packaged optics capabilities.
Representing ASE’s next generation of 3D heterogeneous integration architecture, VIPack™ extends design rules to achieve ultra-high interconnect density and performance. By leveraging advanced redistribution layer processes, embedded integration, and both 2.5D and 3D technologies, the platform enables customers to integrate multiple chips within a single package.
Collectively, these capabilities provide the foundation for highly integrated silicon solutions that optimize clock speed, memory bandwidth, and power delivery while reducing co-design complexity, development cycles, and time to market. VIPack™ delivers the dense horizontal and vertical interconnects required to integrate disaggregated SoCs and high-bandwidth memory for leading-edge AI, ML, HPC, and networking platforms.
Beyond infrastructure and compute, VIPack™ extends into mobile applications through ultra-low-profile system-in-package solutions that streamline RF design iteration, enhance performance, and integrate passives directly within RDL layers. The platform also supports next-generation application processors by enabling thinner form factors while addressing power delivery challenges at advanced silicon nodes.
VIPack™ is evolving new opportunities for customers to innovate across the entire product lifecycle—from design through high-volume manufacturing—while delivering meaningful gains in functionality, performance, and cost efficiency. As AI drives unprecedented complexity and compute intensity, VIPack™ represents a critical leap forward in the advanced packaging technologies required for the next generation of data center and AI system integration.
As we head into 2026 and beyond, demand for computational capability will continue its rapid growth trajectory with energy efficiency becoming a game changer. Advanced packaging will move even further into the strategic spotlight, extending the pace of innovation as traditional scaling stalls.
