Qnity Electronics, a global leader in technology solutions across the semiconductor value chain, announced the introduction of two specialized materials engineered to advance the semiconductor packaging industry: Intervia™ 8540HSP multi-role copper and Cyclotene™ DF6800M dry film photo-imageable dielectric.
These material innovations provide the chemical and structural foundations required to manufacture high-density interconnects, ultra-fine redistribution layer (RDL) tracks, and emerging glass core substrate architectures.
Evolving Packaging Infrastructure for AI and High-Performance Compute
As the restrictions imposed by silicon scaling have now become too cumbersome, the semiconductor industry is rapidly moving from monolithic scaling to heterogeneous integration, where chiplets of various types are stacked together physically with the help of an interposer. This requires high-purity materials, which can support narrow pitch wires with lower parasitic capacitance and also show thermal stability under AI workloads.

“AI is fundamentally changing how chips are packaged-and materials have to evolve just as fast,” said Chuck Xu, President of Interconnect Solutions at Qnity. “As architectures move from shrinking to stacking, we’re focused on enabling that shift with advanced materials that give our customers a clear edge in performance, yield, and long-term reliability. Our advanced materials and process technologies enable next-generation advanced packaging applications across wafer-level packaging, panel-level packaging, and thermal and assembly.”
A Specialized Dual-Material Portfolio for Advanced Interconnects
Qnity’s new chemical and polymer solutions target separate critical layers within modern wafer-level and panel-level advanced packaging workflows:
Intervia™ 8540HSP Multi-Role Copper: Engineered explicitly for the high-volume manufacturing of AI-driven graphics processing units (GPUs) and application-specific integrated circuits (ASICs). This metallization chemistry provides ultra-pure copper deposition for micro-bumps and high-density copper redistribution layers (Cu-RDL). It offers exceptional within-die uniformity (WIDU) and tight control over surface height variation, minimizing mechanical stress and ensuring reliable, fine-pitch electrical contact points.
Cyclotene™ DF6800M Dry Film Dielectric: Developed as a high-reliability insulation layer tailored for next-generation glass core substrates and glass interposers. Glass substrates present a breakthrough alternative to traditional organic laminates due to their dimensional rigidity and ability to house ultra-dense through-glass vias (TGVs). Cyclotene™ DF6800M features an aqueous-developed, photo-imageable chemistry delivered in a dry film format. This allows for flat planarization over pre-patterned metal circuits, precise fine-feature etching, and uniform multilayer build-ups, supporting scalable manufacturing of dense computing architectures.
Live Demonstration at JPCA Show 2026
The company Qnity Electronics stated that both next-generation materials will have their first public display at the upcoming JPCA Show 2026, which is planned for June 10 – 12, at the Tokyo Big Sight Exhibition Hall. Technical experts and semiconductor packaging engineers interested in learning more about the materials should visit Qnity’s booth at number #2C-47.
