AGY, JPS Composite
Materials to produce
glass fiber fabric AGY has partnered with JPS Composite Materials to
manufacture the first North American-based low
coefficient of thermal expansion (CTE) glass fibre fabric
developed specifically for advanced integrated circuit
substrates and next-generation semiconductor packag
ing technologies.
Under the agreement, JPS Composite Materials will
weave the new substrate fabrics at its facility in
Statesville, North Carolina, using AGY’s proprietary L-HDI
ultra-low CTE glass fibre. The fibre is produced at AGY’s
manufacturing site in Aiken, South Carolina. Together,
the companies are creating a fully domestic supply
chain for essential reinforcement materials used in
high-performance semiconductor applications.
“Establishing a North American source for low CTE glass
fibre fabric is a major milestone for the semiconductor
supply chain,” said Patrick Hunter, CCO and President at
AGY. “Our L-HDI glass fibre platform was developed to
meet the growing demands for dimensional stability and
dielectric performance in next-generation IC substrates.
By working with JPS, we are providing a domestic solution
that strengthens supply chain resilience while supporting
innovation in advanced packaging.”
AGY’s L-HDI glass fibre is engineered to deliver ultra-low
CTE, strong dielectric performance and consistent
filament structure required for advanced electronic
laminates and substrates. JPS contributes decades of
expertise in precision weaving and high-performance
fabric production, ensuring the strict construction control
and quality standards needed for semiconductor-grade
materials.
