As modern electronic devices demand ever-greater processing power, data bandwidth, and energy efficiency, the transition toward three-dimensional system-in-package has accelerated across a range of end markets. Innovations in die stacking, through-silicon via formation, and micro-bump interconnections have matured, enabling manufacturers to deliver heterogeneous integration at scale. This introduction sets the stage for examining the drivers behind this paradigm shift, the strategic challenges faced by industry stakeholders, and the pathways leading toward broader adoption of three-dimensional packaging technologies

The landscape of semiconductor packaging has experienced a transformative evolution driven by the convergence of heterogeneous integration, advanced thermal management, and design automation. Traditional interposer-based solutions have gradually given way to true three-dimensional stacking approaches that enable tighter interconnect pitch and reduced data path lengths. As chip designers push beyond the limits of Moores Law, three-dimensional system-in-package architectures provide the means to sustain performance gains through vertical integration rather than solely relying on die shrinks.

Concurrently, the proliferation of data-centric applications-ranging from artificial intelligence inference at the edge to 5G-enabled communication systems-has elevated the demand for highly optimized packaging platforms. Innovative cooling solutions and embedded heat spreaders have emerged to address the thermal challenges inherent in densely stacked dies, while advanced electronic design automation tools offer comprehensive co-design of thermal, power, and signal integrity. These technological shifts are reshaping the fundamentals of packaging, compelling ecosystem participants to reevaluate their end-to-end strategies and invest in capabilities that align with the next generation of three-dimensional integration

In 2025, the United States enacted tariffs on a broad spectrum of semiconductor components and advanced packaging equipment imported from several key manufacturing hubs. These measures have introduced higher input costs for assembly houses and OEMs reliant on external foundry services.
