The collider fits in the palm of your hand<\/h2>\n

Chips have become the battleground of modern innovation, and shrinking such high-powered tools down to nanoscale is a strategic breakthrough. Currently, Taiwan dominates chip manufacturing, accounting for over 60% of global production, with TSMC alone responsible for more than 90% of the world’s most advanced chips.<\/p>\n

China, despite heavy investments, still relies on foreign equipment and lags behind in cutting-edge chip fabrication. Meanwhile, the U.S. has been working to regain control \u2014 investing over $50 billion through the CHIPS Act to bring semiconductor production back home. As lasers shrink to the size of chips<\/strong> and chip wars heat up, the line between science fiction and geopolitical strategy gets thinner by the day.<\/p>\n

U.S. xLight to change semiconductor manufacturing<\/h2>\n

A U.S. startup is developing a new type of EUV light source that could reshape how advanced semiconductors are manufactured \u2014 and challenge the dominance of Europe’s ASML in extreme ultraviolet (EUV) lithography.<\/p>\n

xLight, based in Palo Alto, California, has raised $40 million in Series B funding<\/a> to build a prototype free-electron laser (FEL) capable of emitting EUV light directly. Unlike current systems, which rely on laser-driven plasma<\/strong> sources, xLight’s FEL uses particle accelerator technology to generate high-intensity beams with fewer physical limitations.<\/p>\n

According to the company, the new source could deliver up to four times more EUV power than current systems. That increase would allow for higher throughput and efficiency, while reducing the need for each lithography tool to have its own dedicated light source. The prototype is expected to be operational by 2028.<\/p>\n

ASML currently leads the global market for EUV lithography tools, using laser-produced plasma (LPP) sources. The technology originated in the U.S. at Cymer, a California-based company later acquired by ASML in 2013. While this method has powered the most advanced chip making<\/strong> processes to date, it is widely seen as approaching its physical limits.<\/p>\n

Industry leader considering the approach<\/h2>\n

xLight says its technology<\/a> isn’t just about boosting performance\u2014it could also help keep Moore’s Law alive for decades by enabling even shorter wavelengths of light. The company has reportedly already opened lines of communication with engineers at ASML, a sign that its approach might be taken seriously by the current EUV leader. One notable figure involved is former Intel CEO Pat Gelsinger, who serves as executive chairman of xLight’s board, while Playground Global \u2014 the VC firm he is associated with \u2014 led the company’s Series B round.<\/p>\n

How the product works?<\/h2>\n

xLight’s approach is based on particle accelerator science. Electrons are first generated and then passed through a sequence of magnets<\/strong>\u2014known as undulators\u2014which forces them to emit powerful beams of coherent light. The firm’s CEO and CTO, Nicholas Kelez, who previously led engineering work at SLAC’s Linac Coherent Light Source, says this method opens the door to a more scalable and efficient EUV platform.<\/p>\n

The company sees this effort as a response to growing pressure within the semiconductor industry\u2014particularly around cost, energy requirements, and production capacity. xLight aims to bring FEL-based light sources into commercial chipmaking and strengthen U.S. competitiveness in the field.<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"
