3D InCites Members Reveal Breakthrough Technologies at ECTC 2025

The 75th anniversary celebration of ECTC in Dallas showcases a remarkable evolution in advanced packaging technologies, revealing how semiconductor priorities have dramatically shifted. Rather than the relentless miniaturization of the smartphone era, today’s AI-driven applications demand larger packages with more functionality and sophisticated thermal management solutions.

Glass core substrates emerged as the star technology of the conference, with standing-room-only sessions demonstrating the industry’s intense interest in this promising material platform. The excitement is justified – glass offers superior dimensional stability and enables higher-density interconnects than traditional organic substrates. Meanwhile, co-packaged optics generated similar enthusiasm as engineers tackle the monumental challenge of powering AI server racks that consume between 0.5-1 megawatt each, making energy efficiency a critical concern.
