Taiwan is 180 kilometers wide. On it, a single company—TSMC—manufactures a meaningful portion of the world's advanced semiconductors. When geopolitical analysts worry about global supply chains, they're really worried about Taiwan. A military disruption, a natural disaster, a political crisis—any would immediately constrain the electronics industry globally.

This concentration risk is why India, the US, Europe, and others suddenly care about semiconductor manufacturing in 2026. India's play is explicit: offer $10 billion in subsidies, build fabrication plants, develop supply chains, become a credible alternative to Taiwan for non-leading-edge chips. The ambition is clear. Execution remains messy.

When India announced its semiconductor initiative in 2021, the plan was elegant: leverage government support to attract global chipmakers, build local technical expertise, establish India as a secondary hub. TSMC visited. Intel considered. By 2025, the reality was humbler: Samsung announced a facility in Noida that's smaller and more cautious than initially hoped. Most other commitments evaporated.

The reasons are practical. Semiconductor fabrication is capital-intensive in ways few industries match. A modern fab costs $15-20 billion. It requires electricity so reliable that an outage of a few seconds can damage $100 million in product. It requires workforce expertise that requires years of training. It requires supply chains of specialized equipment that don't yet exist in India.

Take power. Taiwan has redundant power infrastructure. India's grid, despite improvements, still experiences outages. A semiconductor fab can't tolerate intermittent power—the loss would be catastrophic. This means dedicated power generation, which means additional cost and complexity that Taiwan doesn't face.

Or take supply chains. Semiconductor manufacturing depends on specialized equipment: extreme ultraviolet lithography machines that cost $200 million and come from ASML in the Netherlands, ion implantation tools from Japanese suppliers, materials from specialty chemical companies. These clusters exist in Taiwan, South Korea, and to some extent Japan. India is building from zero.

The workforce challenge is more subtle. India has excellent software engineers and IT talent. Semiconductor manufacturing is different—it requires hands-on technical expertise, process control, equipment calibration. The training timeline is years. Samsung's Noida facility will largely import skilled workers from Korea initially, gradually training local staff. This is necessary but expensive and slow.

What's nonetheless happening is real progress. Samsung is building. Micron announced a fab commitment in Gujarat. Smaller facilities for assembly and testing are being established. The government is maintaining subsidy commitments across political cycles—unusually stable for India. International companies are watching.

The most realistic trajectory isn't India becoming another Taiwan but becoming a secondary hub for specific categories. Mature node chips (older technology, large market, lower capital requirements) can feasibly manufacture in India. Display driver chips, power management chips, certain memory—these are realistic. Leading-edge chips for AI and 5G will remain concentrated in Taiwan for at least a decade.

What India can realistically achieve by 2030: 2-3 major fabs operational or under construction, collectively producing perhaps 5-10% of global semiconductor volume in their chosen categories. This is substantial—it represents serious manufacturing capability and reduces dependence on Taiwan. But it doesn't solve the geopolitical vulnerability problem. Taiwan remains critical.

The challenge that might derail this is policy consistency. Indian governments change. Political priorities shift. If the current administration's semiconductor support becomes orphaned when a new government takes over, companies will notice and adjust. TSMC and Samsung are making 10-20 year bets. They need confidence that subsidies and support continue across political cycles. India's history on this is mixed.

There's also a strategic question: if India builds semiconductor capacity, is it for global markets or domestic demand? If it's global, India competes with established players and struggles. If it's domestic, it's protectionist and limits scale. The optimal path—building globally competitive capacity—requires maintaining an open, business-friendly environment while supporting infrastructure development. This isn't impossible but requires discipline India has struggled to show.

The deeper reality is that semiconductor manufacturing is a high-stakes competition among major powers, all realizing simultaneously that Taiwan concentration is dangerous. India, US, Europe, Japan all announced manufacturing initiatives in the same period. This creates competition for investment and talent. India is one player among many, without the inherent advantages that Taiwan developed over decades.

Success isn't impossible. It's just not the story of India replacing Taiwan as the semiconductor hub. It's the more modest story of India becoming a meaningful secondary player, reducing global dependence on one island, and building manufacturing capability that serves both Indian and global markets. That's valuable. But it requires patience, sustained investment, and political consistency. The jury on whether India can manage all three remains out.
