Why Germany’s Chipmaking Mirrors Keep Getting Bigger

Smaller chip features demand bigger, more precise optics. Why? This documentary follows the German mirrors and optical systems that ZEISS develops for ASML's High-NA EUV lithography machines. We explore how extreme ultraviolet light is reflected, why numerical aperture changes the optical design, and what larger assemblies mean for measurement, manufacturing and integration. The story connects a counterintuitive physical mechanism to the practical limits of bringing a new chipmaking process into production. Germany's contribution is precision optics within an international supply chain. ASML integrates the scanners in the Netherlands, and chipmakers must qualify the process for their own products. Company-reported manufacturing milestones are distinguished from universal adoption or independently verified performance. Germany Rewired explores the machines, infrastructure and technologies reshaping Germany. Which engineering challenge should we investigate next? Tell us in the comments.
