AGY, JPS Composite Materials Launch Domestic Production of Low-CTE Glass Fiber Fabrics

AGY and JPS Composite Materials have launched a North American supply chain to produce low‑coefficient of thermal expansion (CTE) glass‑fiber fabric for advanced semiconductor substrates. The partnership pairs AGY’s ultra‑low‑CTE L‑HDI fibers made in Aiken, South Carolina, with JPS’s weaving capability in Statesville, North Carolina. The fabric targets high‑performance IC packaging such as Chip‑on‑Wafer‑on‑Substrate (CoWoS) and System‑on‑Integrated‑Chip (SoIC) platforms. Initial production is underway with customer qualification processes in progress.
