16 IC Package Substrates ABF
The ABF (Ajinomoto Build-up Film) substrate market is in a structural growth phase driven by surging demand for advanced semiconductor packaging in AI/HPC, 5G, and data centers. A severe supply-demand imbalance—reinforced by Ajinomoto’s 30%+ price hike in H2 2026—highlights a chronic shortage that is expected to persist through 2027 and potentially widen to a 42% gap by 2028. This creates pricing power and multi-year visibility for incumbent substrate manufacturers, though high concentration risk, complex manufacturing, and the nascent threat of glass substrates temper the thesis.

Uzasadnienie outlooku
Demand tailwinds from AI supercycle are structural, not cyclical. The supply gap is widening despite record capex, underpinning multi-year pricing power and volume growth for established ABF substrate makers.
