According to Inc., Substrate, a San Francisco startup, has raised over $100 million in funding to challenge ASML’s dominance in semiconductor manufacturing equipment. The company, founded by 34-year-old James Proud, claims its proprietary technology using particle accelerators can cut chip-making costs in half compared to ASML’s massive lithography machines. Backed by Peter Thiel’s Founders Fund and General Catalyst, Substrate has reached a valuation exceeding $1 billion despite ASML having a 10-year head start in the industry. The startup emerges during a period of heightened U.S. government interest in reducing reliance on foreign chip manufacturers, though it faces significant technical and commercial hurdles. This ambitious challenge to one of tech’s most entrenched monopolies raises critical questions about the future of semiconductor innovation.

The ASML Fortress: More Than Just Technology
What makes ASML’s position so formidable isn’t just their technology—it’s their entire ecosystem. The semiconductor industry operates on decades of established relationships with chip manufacturers like TSMC, Samsung, and Intel. These companies have billions invested in ASML equipment and processes. The switching costs for any new technology are astronomical, requiring not just new machines but entirely new manufacturing processes, retrained engineers, and validated production lines. ASML’s extreme ultraviolet (EUV) lithography systems represent the culmination of 30 years of refinement and collaboration with the world’s largest chipmakers.
The Technical Reality Check
While Substrate’s particle accelerator approach sounds innovative, the semiconductor manufacturing process involves hundreds of precisely calibrated steps beyond just lithography. The challenge isn’t just creating patterns on silicon—it’s doing so with nanometer precision, high throughput, and consistent yield across millions of chips. ASML spent decades solving problems like stochastic variation, mask defects, and resist chemistry that new entrants must overcome from scratch. Even if Substrate’s core technology works, they’ll need to develop the entire supporting infrastructure—metrology, software, and service networks—that makes chip production commercially viable.
Geopolitics as an Accelerator
The timing for Substrate’s challenge couldn’t be more opportune from a geopolitical perspective. The CHIPS Act has allocated $52 billion to revitalize American semiconductor manufacturing, creating unprecedented government support for domestic alternatives to foreign suppliers. With ASML Holding based in the Netherlands and subject to export controls, there’s genuine strategic interest in developing American-controlled advanced chip manufacturing capabilities. However, government support alone cannot overcome fundamental technical and commercial barriers—history is littered with well-funded government-backed tech initiatives that failed to achieve market relevance.
The $100 Million Question
While $100 million sounds substantial, it’s pocket change in the semiconductor equipment industry. ASML spends nearly that much every two weeks on research and development. Building, testing, and scaling semiconductor manufacturing equipment requires capital expenditures that typically run into the billions before reaching commercial viability. The funding gap between Substrate’s current position and becoming a credible alternative to ASML is enormous. Even with additional rounds, they’ll be competing against a company that generated over $27 billion in revenue last year and reinvests heavily in maintaining its technological edge.
A More Plausible Strategy
The most realistic path for Substrate isn’t head-to-head competition with ASML’s most advanced nodes, but rather targeting specific niches where their cost advantage could prove decisive. Older process technologies still represent significant market segments, and specialized chips for automotive, industrial, or IoT applications might benefit from cheaper manufacturing without needing cutting-edge performance. Alternatively, they could position themselves as a complementary technology provider rather than a direct replacement, focusing on specific process steps where their approach offers clear advantages. This measured approach would allow them to build credibility and revenue while continuing to develop their technology.
Broader Industry Implications
Even if Substrate achieves limited success, their attempt could have positive ripple effects across the semiconductor ecosystem. The mere existence of a credible challenger might push ASML to accelerate innovation or reconsider pricing strategies. More importantly, it demonstrates that venture capital is willing to back ambitious challenges to entrenched tech monopolies, potentially inspiring other innovators to tackle similarly difficult problems. The ultimate test will be whether Substrate can transition from promising technology to commercially viable solution—a journey that has defeated many well-funded semiconductor startups before them.
