As 2.5D architecture continues to scale, interposers must deliver higher bandwidth, enhanced signal integrity, and efficient power delivery while maintaining yield and long-term reliability.
Meeting these requirements introduces complex integration challenges across wafer- and panel-level processes. Fine-pitch microbump connections between chiplets and interposers must support tighter tolerances and higher reliability. Vertical signal and power routing rely on high-aspect-ratio through-silicon vias (TSVs), while redistribution layers (RDLs) must achieve finer line and space dimensions without compromising yield or manufacturability.
As interposers scale to support larger and more complex chipsets, risks such as warpage, yield loss during assembly, and long-term module reliability become increasingly significant. Advanced assembly techniques, including thermal compression bonding of microbumps, further elevate the need for robust interconnect materials that maintain mechanical stability, low contact resistance, and consistent electrical performance throughout the device lifecycle.
By partnering closely with industry leaders in advanced 2.5D packaging, Qnity’s portfolio enables scalable interposer solutions across silicon, hybrid, and emerging glass and coreless designs, helping engineers and designers achieve precise process control, high yields, and reliable performance as they bring next-generation HPC and AI systems to market with confidence.
