What is xLight working on?

xLight is developing novel lithography techniques using nanometer-scale light beams to etch chip features. The company aims to move beyond the 13.5-nanometer wavelength light used by leading competitor ASML, potentially reaching wavelengths as small as 5-, 4-, 3-, or 2-nanometer using free-electron lasers.

Why is lithography the key to reviving Moore's Law?

As semiconductor firms push the limits of physics, further shrinking atomic-scale transistors has become prohibitively difficult and expensive. The ability to cram in more, even smaller features through advanced lithography would unlock more powerful processors. Gelsinger argues that all other semiconductor innovations—new materials, superconductors, and ferroelectric materials—ultimately depend on lithography progress.

How does Gelsinger evaluate deep tech startups?

Playground's investment team consists of engineers, PhDs, and professors who conduct rigorous tech diligence including interviews and background checks. They assess whether founders can articulate the core hard problem in depth and look to fund the best team on a given topic, recognizing that multiple companies often pursue similar ideas.

Intel's ex-CEO bets on light-based chips to revive Moore's Law

3 Key Points

What happened
Pat Gelsinger, who left Intel as CEO in late 2024, joined venture capital firm Playground Capital as a general partner in March and took a board seat at portfolio company xLight, which develops advanced lithography techniques using nanometer-scale light beams to etch smaller chip features.
Why it matters
Gelsinger believes breakthroughs in lithography—specifically moving beyond the 13.5-nanometer wavelength light that the leading ASML technology uses today—are essential to reawakening Moore's Law, the decades-old prediction that transistor density doubles roughly every two years. As AI demands surge, semiconductor performance has hit a physics wall; novel light-based approaches could unlock the next generation of more powerful processors without the prohibitive cost of further atomic-scale shrinking.
What to watch
xLight is exploring free-electron lasers that could enable wavelengths as small as 5-, 4-, 3-, or 2-nanometer, and aims first to integrate its light source with ASML's existing machines to improve them. Gelsinger contends that most venture firms have shifted toward deep tech but lack the technical expertise to pick winners; his deep semiconductor background and assembled team of engineers and PhDs is meant to change that.

Context & Analysis

Gelsinger's pivot from Intel to venture capital marks a strategic recalibration at a inflection point in both semiconductors and AI. During his 100-day deliberation after leaving Intel in late 2024, he weighed government roles, academia, CEO positions, and private equity before settling on venture—a choice he framed as driven by personal preference for advancing frontier technology over pure financial returns. The semiconductor industry's timeline itself has accelerated: Gelsinger notes that projections moved from hitting $1 trillion（約160兆円） in revenue by 2030 to achieving that milestone as soon as next year, a shift he attributes directly to AI's surge in demand.

The lithography bet reflects a deeper conviction that incremental improvements to existing chip design will not meet AI's power and performance needs. While Nvidia's GPU dominance in AI training is undisputed, Gelsinger sees inference—the repeated use of trained models—as an emerging frontier where diverse chip architectures from multiple vendors could thrive. His focus on xLight and light-based manufacturing is not framed as competition with ASML but as complementary: the first step is integrating xLight's light source into ASML's existing machines to make them better. This reflects both humility about the scale of ASML's installed base and confidence that solving lithography unlocks everything downstream.

Gelsinger also emphasizes that most venture firms, despite rushing toward deep tech in response to AI disruption, lack the technical depth to distinguish between viable breakthroughs and dead ends. His assembled team—engineers, PhDs, and professors—is presented as a corrective. The combination of his Intel pedigree, a portfolio spanning lithography, memory architecture, and energy infrastructure (including nuclear upgrades), and his stated mission to make AI "10,000 times better, not 10 times" positions Playground as a bet on the hardware stack underneath AI, not software abstractions.
