Heterogeneous Integration Roadmap (HIR)

10:00 am - 10:30 am

Heterogeneous Integration (HI) — the integration of separately manufactured components into a higher-level System-in-Package delivering enhanced functionality and improved operating characteristics — is now central to continued advances in computing and communications. Sustaining this trajectory requires advanced packaging to scale along multiple vectors simultaneously, and, as argued in Nature Reviews Electrical Engineering (Mahajan, Chen, Thompson, et al., 2026), depends on comprehensive roadmaps that align systems architects, packaging specialists, and semiconductor technologists to common goals. Systematic road-mapping is needed both to mature the correct building blocks in advance of demand and to expose integration challenges that are complex, time-consuming, and frequently under-scoped.

This paper presents the Heterogeneous Integration Roadmap (HIR), a volunteer-driven, open-access, systems-application-driven effort blending market pull with technology push. We describe its four-part structure: target systems (HPC/AI and data centers, mobile, aerospace and defense, medical, autonomous automotive, IoT, with space electronics newly added); building blocks spanning integrated photonics, power electronics, MEMS/sensors, and 5G/6G+ mixed-signal integration; technology integration areas including SiP, 2D/3D interconnects, and wafer- and panel-level packaging; and cross-cutting technical areas, including a new metrology chapter. We report the 2025 Edition's 25 updated chapters and the accelerated 2026 schedule.

Building blocks: photonics, power, MEMS, 5G/6G+
Integration platforms: SiP, 3D interconnects, wafer/panel packaging
Technical areas: materials, thermal, co-design, new metrology
Driving systems: AI/HPC, mobile, automotive, IoT, space
