E&R Engineering advances glass substrate pilot production to 2H27

Accelerating glass substrate pilot production to 2H27 signals that AI-driven demand for high-density interconnects is outpacing organic substrates’ roadmap. Technically, this forces a leap in lithography alignment, laser drilling precision, and CTE control—while pressuring material suppliers to fast-track low-alpha glass formulations. On compliance, the U.S., Japan, and South Korea are increasingly restricting critical equipment exports under 'advanced packaging' pretexts, extending lead times and inflating localization costs for firms in Taiwan, China and mainland China. Strategically, TSMC and Intel will likely rush CoWoS and Foveros capacity, while Samsung may be forced to revise its I-Cube timeline. Within 18 months, glass substrates will shift from optional to essential, triggering an equipment order surge, material qualification battles, and regional subsidy races—ultimately transforming advanced packaging into a fab-like, capital-intensive domain with sharply raised entry barriers.
