A secret lab in China has reportedly developed a prototype extreme ultraviolet (EUV) lithography system through reverse engineering existing scanners from ASML, aiming to create prototype chips by 2028. The system uses a laser-produced plasma method similar to ASML's technology but is larger and currently unable to produce usable chips due to challenges with precision optical systems. The Chinese team includes former ASML engineers and recent graduates, with efforts to reverse engineer components monitored closely. While China aims for chip prototypes by 2028, realistic expectations suggest a timeline closer to 2030, highlighting the complexity and challenges of replicating advanced lithography technology.

Pentagon budget documents reveal it's pursuing containerized 300kW+ laser weapons, ambitious Joint Laser Weapon System designed to shoot down cruise missiles — system part of $17.9 billion Golden Dome missile-defense initiative

The Pentagon is accelerating the development of a Joint Laser Weapon System (JLWS) to shoot down cruise missiles, part of the $17.9 billion Golden Dome missile-defense initiative. The system aims to integrate high-energy laser subsystems for testing in naval environments, with a focus on cruise missile defense. The Pentagon is pursuing a containerized laser architecture capable of scaling beyond 300 kilowatts, a significant escalation in power. The JLWS initiative reflects the military's growing emphasis on directed-energy systems and could lead to a fully functional weapon system in the near future.

US stops exports of tools to China’s number two chip maker — Hua Hong and Huali Microelectronics reportedly on the cusp of starting a 7-nm fab in Shanghai

The US Department of Commerce has instructed toolmakers to cease exports to Hua Hong, China's second-largest chipmaker, which is gearing up to establish a 7-nm production line in Shanghai. This move is part of the US strategy to impede China's semiconductor self-sufficiency efforts. Companies like TSMC and ASML have also faced restrictions in providing advanced services to Chinese tech firms. The ban on exports could strain US-China relations, impacting both Chinese companies' progress and potential losses for American toolmakers.
