In the high-stakes world of semiconductor manufacturing, dominated by billion-dollar behemoths like ASML, a scrappy San Francisco start-up is making waves with a bold promise: cheaper, faster, and more accessible computer chips. The company, named Substrate, isn’t just tinkering at the edges—it’s aiming to disrupt the very foundation of how chips are made.

Substrate: The David in a Goliath Industry
Founded just three years ago, Substrate has flown under the radar while quietly assembling a team of ex-Intel, TSMC, and Applied Materials engineers. Now, with $120 million in Series B funding and a prototype tool already in testing, the start-up is stepping into the spotlight. Their mission? To challenge the near-total control that ASML—a Dutch firm valued at over $300 billion—holds over the most advanced chipmaking equipment.
How Substrate Plans to Cut Chip Costs
At the heart of Substrate’s strategy is a radical rethinking of photolithography—the process used to etch microscopic circuits onto silicon wafers. While ASML’s extreme ultraviolet (EUV) machines cost upwards of $200 million each and take over a year to build, Substrate claims its new approach uses modular, software-defined hardware that slashes both cost and lead time.
“We’re not trying to out-engineer ASML on their terms,” said CEO Lena Cho in an exclusive interview. “We’re changing the game entirely. Our system is 60% cheaper to produce and can be deployed in weeks, not years.”
The company’s secret lies in leveraging advances in computational optics and AI-driven calibration, reducing reliance on ultra-precise mechanical components that drive up costs and complexity.
The ASML Monopoly and Why It Matters
ASML currently supplies over 90% of the world’s EUV lithography tools—machines so complex they’re considered national strategic assets. The U.S., South Korea, Taiwan, and the EU all depend on ASML for next-gen chips powering everything from smartphones to AI data centers.
This concentration of power has raised concerns about supply chain fragility, especially amid U.S.-China tech tensions. Any disruption at ASML can ripple across the global economy. Substrate’s emergence is being watched closely by policymakers in Washington and Brussels as a potential path to diversification.
Industry Reaction and Challenges Ahead
Not everyone is convinced. Industry veterans point out that chipmaking isn’t just about cost—it’s about nanometer-level precision. “You can’t just ‘disrupt’ physics,” said one senior engineer at a major foundry, who asked to remain anonymous. “Yield rates and defect control are everything.”
Substrate acknowledges the hurdles. Its current prototype targets chips at the 28-nanometer node—older but still widely used in automotive and industrial electronics. The real test will come when it attempts to scale to 5nm or 3nm processes, where ASML’s dominance is absolute.
What This Means for Tech Consumers
If Substrate succeeds, the ripple effects could be massive. Cheaper chipmaking tools could lower barriers to entry for new semiconductor fabs, especially in emerging markets. Over time, this could lead to more competition, faster innovation, and—potentially—lower prices for everything from electric vehicles to smart home devices.
Key Players in Advanced Chipmaking
