The global tech press is currently swooning over a beautifully packaged fantasy. The narrative goes like this: Japan and India, fresh off their historic collaboration on the Delhi Metro, are now ready to port that exact same bilateral magic over to artificial intelligence and semiconductor manufacturing.
It sounds poetic. It sounds strategic. It is also completely delusional. Recently making news in this space: The Real Reason Domestic Police Are Training to Fight Off Cheap Drones.
Comparing a mass transit railway system to a sub-5-nanometer semiconductor fabrication plant is like assuming someone can perform open-heart surgery because they are excellent at digging ditches. They are both engineering feats, yes, but the underlying physics, economics, and supply chain realities share absolutely zero DNA.
The lazy consensus among policymakers in New Delhi and Tokyo is that diplomatic goodwill and capital can brute-force a domestic silicon ecosystem. They are wrong. If India and Japan continue down this path of treating chip manufacturing like a public infrastructure project, they are going to burn through tens of billions of dollars of taxpayer money for nothing. Additional information regarding the matter are detailed by MIT Technology Review.
The False Equivalence of Infrastructure vs. Silicon
To understand why this alliance is fundamentally flawed, we have to dismantle the myth of the Delhi Metro success story.
The Delhi Metro Rail Corporation (DMRC) succeeded because it was a localized, civil engineering project supported by Japanese Official Development Assistance (ODA) loans and project management expertise. It relied on fixed variables: steel tracks, concrete viaducts, tunneling boring machines, and localized real estate acquisition. Once the tracks are laid and the rolling stock is delivered, the system enters a predictable operational phase. It is an insular project. A train running in Delhi does not have to compete in real-time with a train running in Tokyo or New York.
Semiconductors operate on the exact opposite plane of reality.
A semiconductor fab is not a localized asset; it is a hyper-sensitive node in a brutal, hyper-globalized supply chain.
- The Depreciation Trap: In civil infrastructure, assets depreciate over decades. In silicon fabrication, millions of dollars worth of Lithography equipment becomes obsolete in 36 to 48 months. If your yield rates are not competitive from day one, you are burning capital at a rate that would make a hyper-growth software startup vomit.
- The Supply Chain Chokepoint: You cannot build a self-contained chip industry inside a single country's borders. A single modern chip requires tools from the Netherlands (ASML), chemicals from Japan (Tokyo Ohka Kogyo), design software from the US (Synopsys), and packaging in Taiwan (ASE).
- The Talent Chasm: Managing thousands of construction workers pouring concrete for a subway line requires exceptional project management. Managing a cleanroom where a single speck of dust can ruin a $100 million wafer lot requires an ultra-specialized workforce that takes decades to cultivate.
I have watched sovereign funds dump billions into "prestige fabs" only to realize they bought an incredibly expensive museum of last-generation equipment because they couldn't hire the five hundred hyper-specialized engineers needed to run it.
Japan's Semiconductor Amnesia
The partnership assumes Japan brings the technological powerhouse status to the table while India brings the scale and software talent. This completely misreads Japan's current position in the global semiconductor hierarchy.
Japan does not dominate chip manufacturing anymore. It hasn't since the late 1980s.
When the US cracked down on Japanese memory chips via the 1986 Semiconductor Agreement, and companies like Samsung and TSMC mastered the foundry model, Japan’s market share in fabrication collapsed from over 50% to less than 10%. Japan’s current internal savior project, Rapidus, is currently burning through billions in government subsidies trying to leapfrog straight to 2-nanometer production. It is a massive gamble that many industry veterans privately admit is a long shot.
Japan absolutely dominates specific niche areas: photoresists, silicon wafers (Shin-Etsu), and specialized equipment (Tokyo Electron). But it does not possess the turnkey foundry operational expertise of TSMC or even Intel.
So when India partners with Japan for "chip manufacturing," New Delhi is partnering with a nation that is itself trying to relearn how to build chips at scale. It is the blind leading the blind.
India's Misguided Pursuit of Leading Edge Silicon
India's current semiconductor policy is heavily incentivizing the wrong part of the stack. The government's $10 billion subsidy package is designed to lure big-name fabrication plants to Indian soil.
This is an expensive mistake. India should not be chasing leading-edge or even mainstream logic fabs right now. The infrastructure vulnerability is too high.
Let's talk about the brutal operational realities of a fab. A standard logic fab consumes millions of gallons of ultra-pure water daily and requires a completely uninterrupted, spike-free power grid. A power fluctuation lasting a fraction of a second can ruin an entire production run. While India's national grid has improved drastically, the hyper-redundant, ultra-stable power architecture required for a sub-28nm fab is non-existent without massive, dedicated, and expensive localized generation infrastructure.
Instead of trying to build a trophy fab to boast about on the geopolitical stage, India should be doubling down on what it actually does best: chip design.
Nearly 20% of the world’s semiconductor design engineers are located in India, concentrated in hubs like Bengaluru and Hyderabad. Yet, these engineers work for foreign multinationals (Qualcomm, Nvidia, Intel, AMD). The intellectual property they generate leaves the country, only to be imported back as finished silicon.
If New Delhi took that $10 billion package and used it to subsidize local fabless chip startups, domestic electronic design automation (EDA) tools, and specialized RISC-V architecture development, it would create a high-margin, asset-light tech powerhouse. Instead, they want to build factories that require importing foreign equipment, foreign chemicals, and foreign management to produce low-margin legacy chips.
Dismantling the "People Also Ask" Consensus
Whenever this topic arises, the same naive questions dominate the discourse. Let's answer them honestly.
Can India become the next Taiwan?
No. Not in the next two decades. Taiwan’s dominance is not just about TSMC; it is about an entire geographical cluster. In Hsinchu Science Park, the design firm, the mask shop, the chemical supplier, the fab, and the packaging house are literally down the street from one another. This spatial proximity creates an absurdly fast iteration cycle. Moving components across states in India via fragmented logistics networks destroys the tight feedback loops required for high-yield silicon manufacturing.
Will the India-Japan AI alliance break China's monopoly?
China does not have a monopoly on advanced AI or advanced semiconductor manufacturing; ASML, TSMC, and Nvidia do. China has a near-monopoly on critical raw materials (gallium, germanium, rare earths) and legacy-node production (28nm and above). An India-Japan alliance focused on high-level AI software frameworks does nothing to solve the hardware dependency on Western IP and Taiwanese manufacturing.
The Downside of the Contrarian Reality
If India shifts its focus away from fabrication and toward design, it faces a distinct downside: it remains strategically vulnerable to a geopolitical crisis in the Taiwan Strait. If Taiwan goes offline, a fabless India still starves for silicon.
But here is the uncomfortable truth: building a couple of low-yield, heavily subsidized 28nm legacy fabs in Gujarat or Assam will not save India from a Taiwan crisis anyway. Those fabs would still rely on imported components and materials that would be choked out in a global trade freeze.
The goal of absolute silicon self-reliance is a romantic lie told by politicians. Total self-reliance in semiconductors is mathematically and logistically impossible for any single nation or bilateral alliance on earth today.
Stop trying to build a duplicate TSMC in the subcontinent using a playbook designed for subway systems. Turn off the subsidy spigot for foreign manufacturing conglomerates. Fund a thousand domestic fabless design startups instead.
Play the game on the software and architecture layer where you actually have a competitive advantage, or prepare to watch billions in capital evaporate in the cleanrooms of empty vanity projects.
