Tiny Japan Firm Helps to Crack Code for Next-Gen Computer Chips

Chipmakers have spent two decades pouring investment into a revolutionary new technique to push the limits of physics and cram more transistors onto slices of silicon. Now that technology is on the cusp of going mainstream, thanks to a secretive Japanese company that's mastered the skill of manipulating light for applications from squid fishing to cinema projection. From a report: Ushio announced July it had cleared a key milestone, perfecting the powerful, ultra-precise lights needed to test chip designs based on extreme ultraviolet lithography or EUV, the process through which the next generation of semiconductors will be made. With that, the Japanese company became a major player in future chipmaking. "The infrastructure is now mostly ready," Chief Executive Officer Koji Naito said in an interview. "Testing equipment was one of the things holding back EUV. With that piece in place, production efficiency and yields can go up." Ushio's advances cement its position among a coterie of little-known Japanese companies indispensable to the production of the world's consumer electronics. The Tokyo-based company developed a light source for equipment used to test what are known as masks: glass squares slightly bigger than a CD case that act as a stencil for chip designs. These templates have to be absolutely perfect, as even a tiny defect in one of them can render every chip in a large batch unusable.
