2.5D AND 3D PACKAGING MARKET TRENDS

Increasing Adoption of Chiplet-Based Heterogeneous Integration is Reshaping Advanced IC Package Architectures

Semiconductor manufacturers are increasingly replacing large monolithic system-on-chip designs with chiplet-based architectures. These architectures divide processors, memory controllers, I/O functions, accelerators, cache, RF components, and security functions into smaller dies before recombining them through 2.5D interposers, embedded bridges, or 3D stacking. This approach allows performance-critical compute chiplets to use advanced process nodes while analog, I/O, and control dies can be manufactured using more cost-effective mature nodes. This improves design flexibility, yield potential, intellectual-property reuse, and product customization.

ASE identifies heterogeneous integration as a means of combining chiplets manufactured using different process technologies within a single optimized package. Meanwhile, TSMC’s 3DFabric portfolio uses CoWoS, InFO, and SoIC technologies to support both side-by-side and vertically stacked heterogeneous systems.

The increasing density of these multi-chip systems is reflected in Intel Foundry’s objective of integrating approximately one trillion transistors within a package by 2030, using technologies such as EMIB and Foveros. This supports the broader ecosystem transition.

• In August 2025, the UCIe Consortium released the UCIe 3.0 specification with data rates of up to 64 GT/s, double the maximum rate of UCIe 2.0. This aims to improve bandwidth density, power efficiency, and interoperability across multi-vendor chiplets.

Consequently, chiplet adoption is transforming advanced packaging technologies from a back-end assembly process into a central system-design technology. This is directly increasing demand for 2.5D and 3D integration, high-density die-to-die interconnects, hybrid bonding, and package-level co-design.
