Advanced packaging materials
BOTTLENECKResonac dominates specialty underfill and TIM supply for AI accelerator packaging, and qualifying alternative chemistry takes years of reliability testing.
Thermal interface materials, underfill epoxies, solder bumps, die-attach films, and encapsulants used in advanced packaging. TIM and underfill quality directly affects heat dissipation and reliability of high-power AI accelerators. Specialty underfill formulations command premium pricing; market reached $810 million in 2024.
Specialised materials consumed in advanced packaging operations beyond substrate and wire; covers thermal interface materials (TIMs), underfill epoxies, bumping/solder materials, die-attach films/paste, and encapsulants.
What the evidence shows
A single advanced substrate production line requires $500M to $2B investment, creating long lead times for capacity expansion.
