"Electronic resin" is not one material. It is a family of electronic-grade polymers — epoxy molding compounds, laminate resins, build-up films, and photoresists — defined less by what they are made of than by the electrical, thermal, and dimensional numbers they must hit.

An AI chip isn't just bigger than an ordinary chip — it passes through more lithography, etch, clean, and polish cycles, each consuming ultra-high-purity photoresist, CMP slurry, electronic-grade HF, sulfuric acid, and PGMEA at parts-per-trillion purity. A fact-based map of why this supply chain is short, hard to switch suppliers on, and now visibly tightening.
