According to Gizmodo, Substrate, a U.S.-based chip startup, recently raised $100 million from prominent backers including Peter Thiel’s Founders Fund, General Catalyst, and CIA-backed In-Q-Tel. The company aims to revolutionize the semiconductor industry through complete vertical integration, owning the entire manufacturing process rather than relying on the current global supply chain that heavily depends on Asian production. Co-founder James Proud, described as a Thiel protégé, admits the plan sounds “far fetched” but promises to return “the United States to dominance in semiconductor production” using advanced X-ray lithography technology. The company has reportedly received attention from the Trump administration amid broader efforts to reshore chip production, though industry veterans remain skeptical about the sustainability of vertical integration in this business.

The Vertical Integration Gamble That History Rejected
Substrate’s approach represents a dramatic departure from decades of semiconductor industry evolution. The modern chip industry abandoned vertical integration precisely because the complexity and capital requirements became overwhelming. Companies like Intel, TSMC, and Samsung evolved toward specialization because maintaining competitive advantage across design, fabrication, packaging, and testing required unsustainable investment. The vertical integration model Substrate proposes would require mastering multiple disciplines that even industry giants struggle with simultaneously. What’s particularly challenging is that semiconductor manufacturing improvements have historically followed exponential cost curves – each new process node becomes dramatically more expensive to develop while delivering diminishing returns.
The Unforgiving Reality of Global Supply Chains
The current semiconductor supply chain didn’t evolve by accident – it represents decades of optimization for cost, expertise, and efficiency. As research shows, the Indo-Pacific region has developed deep specialization across different manufacturing stages, creating ecosystem advantages that can’t be easily replicated. Southeast Asia’s role in driving global innovation and supply chains represents generations of accumulated knowledge and infrastructure. Attempting to rebuild this entire ecosystem within a single company ignores the fundamental economics that drove specialization in the first place. The capital required to compete across multiple manufacturing domains simultaneously would be astronomical, likely requiring tens of billions more than their current $100 million raise.
The Political Dimension and Long-Term Viability
The involvement of In-Q-Tel and reported Trump administration interest highlights the national security dimension of this effort. While reshoring semiconductor production addresses legitimate geopolitical concerns, it doesn’t solve the economic viability question. Previous attempts at government-supported chip initiatives have struggled because semiconductor manufacturing success depends on continuous innovation and cost competitiveness, not just initial funding. The economic realities of global competition mean that even with political support, Substrate would need to achieve cost parity with established Asian fabs that benefit from scale, experience, and specialized supply ecosystems. The company’s proposed “advanced X-ray lithography” faces particular skepticism, as extreme ultraviolet (EUV) lithography alone required decades and hundreds of billions in collective industry investment to mature.
A Realistic Outlook for Disruption
While Substrate’s ambition is commendable, the more likely path to U.S. semiconductor resurgence involves targeted innovation rather than comprehensive vertical integration. Successful disruption in capital-intensive industries typically comes from focusing on specific technology gaps or process improvements, not attempting to rebuild entire ecosystems. The company might find more success by partnering with existing players to commercialize their lithography technology rather than attempting the near-impossible task of competing across the entire manufacturing stack. Given the track record of Peter Thiel investments in ambitious technology companies, Substrate may secure additional funding, but the fundamental economic and technical barriers suggest this particular approach to vertical integration faces nearly insurmountable challenges in today’s hyper-specialized semiconductor landscape.
