Thermal management has moved from a downstream consequence of packaging decisions to a determinant of them. Power density, not device count, now sets the pace: GPUs running AI workloads dissipate heat fluxes on the order of 140 W/cm², while three-dimensional architectures record average fluxes near 300 W/cm² with localised hotspots between 500 and 1,000 W/cm². Single-package thermal design power has passed the kilowatt level and is advancing toward the 3,000–5,000 W range. The binding constraint is the accumulated resistance of a conventional thermal stack — silicon, metal interconnect, micro-bumps, underfill, TIM1, lid, TIM2, cold plate. Two levers are available: shortening the path and reducing interfacial resistance, or expanding the area available for heat exchange. Both are being pursued simultaneously, and the boundary between "material" and "cooling system" has effectively dissolved inside the package.

Package area growth is the dominant volume driver. The 5.5× reticle-scale CoWoS_L platform entered volume production in 2026 carrying around twelve HBM3E or HBM4 stacks, with roughly 9.5× reticle-scale packages expected by 2027. Full silicon interposers face yield and cost limits beyond about 3.3× reticle, pushing the industry toward embedded silicon bridges, glass substrates and panel formats — each of which makes warpage and CTE mismatch, and therefore bond line uniformity, harder to control.

Several developments reshaped the field through mid-2026. TSMC is integrating microfluidic cooling into its 3DFabric platform, bringing cooling into design-technology co-optimisation alongside power delivery and interconnect. Micro-channel lids have emerged as the transitional architecture, retaining a qualifiable TIM1 interface while moving coolant close to the die. Thermal structures have migrated inside the memory stack: SK hynix's iHBM embeds integrated cooling elements at the die-to-die physical layer, claiming over 30% lower thermal resistance while remaining compatible with existing mass reflow molded underfill processes, and Samsung's Heat Path Block targets the same hotspot, with the HBM5 base die moving to a 2 nm process.

Materially, liquid metal has found a manufacturable form through confinement — fibre-matrix, elastomer-embedded droplet and hybrid dam architectures — rather than free application, addressing pump-out, leakage and aluminium compatibility. Engineered diamond has moved toward manufacturability via CMOS-compatible low-temperature growth and bond-ready surfaces, though grain structure remains decisive: only microcrystalline and single-crystal grades deliver headline conductivity. The supplier base is consolidating, narrowing the qualified field at the high-performance end precisely as requirements become more demanding.

The Global Market for Thermal Management Systems and Materials for Advanced Semiconductor Packaging 2027-2037 is a comprehensive assessment of the materials, hardware and cooling architectures that determine how much power an advanced package can dissipate. Forecasts run to 2037 in constant 2025 US dollars, modelled across three layers — thermal interface materials, package-level thermal hardware, and in-package and direct-to-silicon cooling — with all segmentations reconciling to a single consistent total.
