Why Advanced Chip Manufacturing Is Hard for New Hubs

Advanced chip manufacturing is difficult for new semiconductor hubs because it demands an extreme combination of capital, specialized equipment, ultra-pure materials, and a deep ecosystem of suppliers and skilled engineers that takes decades to build. Even with billions in government subsidies, a new hub must overcome technical, logistical, and human-capital barriers that incumbents like Taiwan, South Korea, and the US have spent 30+ years perfecting. This article explains the core challenges, the role of extreme ultraviolet (EUV) lithography, the cost structure, and why ‘just building a fab’ is only the first step.

Background: Why Semiconductor Hubs Are Concentrated

Semiconductor manufacturing is one of the most concentrated industries on Earth. Over 90% of the most advanced logic chips (below 10 nm) are made in Taiwan by TSMC, with Samsung and Intel accounting for most of the rest. This concentration is not accidental; it results from a self-reinforcing cycle: early investment created a skilled workforce, which attracted more suppliers, which lowered costs, which funded more R&D. New hubs lack this ecosystem, so every component—from photoresist chemicals to ultra-pure water systems—must be imported or built from scratch, raising costs and slowing ramp-up.

Governments have tried to break this cycle. The US CHIPS Act, the European Chips Act, and Japan’s semiconductor strategy all aim to create new hubs. But even with billions in subsidies, the physics and economics of chipmaking remain brutally hard. A new fab can cost $10–$20 billion, and it takes 3–5 years to build and qualify. By then, the technology has moved on, so the new hub is already behind.

How Advanced Chips Are Made: The Process

Advanced chips (like those in smartphones and AI accelerators) are built on silicon wafers through a process of layering, patterning, and etching that repeats hundreds of times. The key steps are:

• Design – Using electronic design automation (EDA) tools to create a blueprint with billions of transistors.
• Photomask creation – Making a stencil of each layer using electron-beam lithography.
• Deposition – Growing or depositing thin films of materials like silicon dioxide or metal.
• Photolithography – Transferring the pattern from the mask onto the wafer using light.
• Etching – Removing material where the pattern is open, using plasma or chemicals.
• Doping – Implanting impurities to change electrical properties.
• Metallization – Adding copper or tungsten interconnects to link transistors.

Each step must be perfectly aligned to the previous one, with tolerances measured in nanometers (a human hair is about 80,000 nm wide). A single dust particle can ruin an entire wafer, so cleanrooms are class 1 or better, meaning fewer than one particle per cubic meter. This requires advanced air filtration, special gowns, and constant monitoring.

The EUV Lithography Bottleneck

The most critical and difficult step is photolithography, specifically extreme ultraviolet (EUV) lithography for nodes below 7 nm. EUV uses light with a wavelength of 13.5 nm, which is absorbed by almost everything, so it must be generated in a vacuum and focused with mirrors coated in molybdenum/silicon multilayers. The machines are made exclusively by ASML, a Dutch company, and each one costs about $150–$200 million. They weigh 180 tons, require 1 MW of power, and are so complex that only a handful of engineers worldwide can install them.

New hubs cannot simply buy EUV machines; they must also secure the supply of ultra-pure tin (used to generate the plasma), the photoresists that work with EUV, and the pellicles (protective membranes) that prevent defects. ASML has a limited production capacity, and its customers (TSMC, Samsung, Intel) have long-term contracts. A new hub may wait years for delivery, and even then, the surrounding infrastructure—such as the cleanroom and the special power systems—must be ready.

Costs and Economies of Scale

The cost of a leading-edge fab is staggering. A 5 nm fab costs around $10–$15 billion, and a 3 nm or 2 nm fab can exceed $20 billion. This includes the building (which is often 2–3 stories tall to accommodate the ductwork and cleanroom), the equipment (lithography, etching, deposition tools), and the initial wafers for qualification. Operating costs are also high: a single fab can consume as much electricity as a small city, and the ultra-pure water (UPW) system produces millions of gallons per day.

To recoup these costs, a fab must run at high utilization (above 80%) and sell millions of wafers per year. New hubs often start with low volume, so their cost per chip is much higher. They also face the problem of yield—the percentage of good dies per wafer. Early on, yields may be 50–70%, which is unprofitable. It can take months or years to improve yield to 90%+ through process tuning, which requires experienced engineers who are in short supply.

Human Capital and the ‘Brain Drain’ Problem

Chip manufacturing is not just about machines; it requires a highly specialized workforce. Process engineers need PhDs in materials science, electrical engineering, or physics. Equipment technicians need years of training to maintain tools that cost millions. The semiconductor industry employs about 300,000 people in the US alone, but many are nearing retirement. New hubs must either poach workers from existing fabs (which is expensive and creates a zero-sum game) or train new ones, which takes 3–5 years.

Moreover, the knowledge is often tacit—it lives in the heads of engineers who have solved specific problems. TSMC’s ‘secret sauce’ is its manufacturing know-how, accumulated over decades of tweaking processes. A new hub cannot simply copy a recipe; it must develop its own, which requires trial and error. This is why TSMC’s Arizona fab, despite billions in investment, has faced delays and labor disputes—it is not just about building a building, but about transferring a culture of precision.

Common Problems and Misconceptions

A common misconception is that building a fab is like building a car factory: you pour concrete, install robots, and start producing. In reality, the complexity is orders of magnitude higher. Here are common problems new hubs face:

• Supply chain gaps – Even if the fab is built, it needs hundreds of specialty chemicals, gases, and spare parts that are only made in a few places (e.g., Japan for photoresists, US for gases). A single missing valve can halt production.
• Water and power – A fab needs enormous amounts of ultra-pure water (UPW) and reliable electricity. In water-scarce regions, this is a political and environmental issue.
• Yield ramp – Getting from ‘first wafer’ to ‘high yield’ can take 12–18 months, during which the hub is losing money.
• Intellectual property – New hubs must navigate a web of patents covering process steps, materials, and equipment. Licensing can be costly or impossible.

Another misconception is that government subsidies are enough. While subsidies help with capital costs, they don’t solve the operational challenges. For example, the US CHIPS Act provided $39 billion in incentives, but the first big project (TSMC Arizona) has struggled with labor shortages and cultural clashes. Money cannot buy experience.

Comparison with Mature Hubs

To understand the difficulty, compare a new hub with an existing one like Taiwan’s Hsinchu Science Park. Hsinchu has been operating since 1980, so it has:

• Thousands of experienced engineers who have worked on multiple process nodes.
• A dense network of suppliers (chemicals, gases, equipment) within a 50 km radius, enabling just-in-time delivery.
• Established relationships with equipment vendors, ensuring priority for new tools.
• A culture of rapid problem-solving, where engineers share knowledge informally.

A new hub lacks all of these. Even if it builds a state-of-the-art fab, it must import most supplies, which adds lead times and costs. It must also train its workforce from scratch, which is slow and error-prone. The result is that new hubs typically take 5–10 years to reach profitability, if they ever do. Some, like Singapore’s and Israel’s, have succeeded by focusing on niche areas (e.g., analog chips, memory) rather than leading-edge logic.

Alternatives and Future Outlook

Given these challenges, some new hubs are choosing to focus on mature nodes (28 nm and above) rather than advanced ones. These chips are used in cars, appliances, and industrial equipment, and they are less demanding. For example, the US is building fabs for 28 nm chips in Texas and Arizona, which are easier to ramp. However, even mature nodes require significant investment and expertise.

Another alternative is to specialize in packaging and testing, which is less capital-intensive. Advanced packaging (like chiplet integration) is becoming more important, and new hubs can compete there. Finally, some countries are exploring ‘open-source’ chip designs (like RISC-V) to reduce design costs, but manufacturing remains the bottleneck.

The future is uncertain. As Moore’s Law slows, the cost of each new node increases, making it harder for new entrants. However, the geopolitical push for supply-chain resilience may drive more investment, and new technologies like extreme ultraviolet (EUV) are becoming more accessible as ASML increases production. But for now, advanced chip manufacturing remains one of the hardest industrial challenges on the planet.

Frequently Asked Questions

Why can’t a new hub just buy the same equipment as TSMC?

They can, but equipment is not enough. The process recipes, the materials, and the expertise are not for sale. TSMC’s advantage is in how it uses the equipment, which is proprietary. Also, ASML’s EUV machines are in limited supply, and existing customers get priority. Even if a new hub gets the machines, it must develop its own process, which takes years.

How long does it take to build a new semiconductor fab?

It typically takes 3–5 years to build and equip a fab, and another 1–2 years to qualify it for production. Reaching high yields can take another year. So from groundbreaking to profitable production, it can be 5–8 years. This is why governments are eager to speed up permitting, but technical challenges remain.

What is the biggest single challenge for a new hub?

Human capital. Machines can be bought, but skilled engineers cannot. A new hub needs hundreds of process engineers, equipment technicians, and managers who understand semiconductor manufacturing. This expertise is concentrated in a few regions, and attracting it to a new hub is difficult and expensive.

Can a new hub start with older technology and catch up later?

Yes, but it’s risky. Older nodes (like 28 nm) are easier to make and have stable demand, but they are also more commoditized, with lower margins. Catching up to leading-edge nodes is nearly impossible because the R&D cost is enormous and the incumbents keep moving forward. Some hubs, like China’s SMIC, have tried this approach but face restrictions on buying EUV machines.

Why do some countries succeed while others fail?

Success depends on a combination of factors: a strong education system, government support, a stable business environment, and access to international supply chains. Singapore and Israel succeeded by focusing on niche markets and leveraging their existing tech ecosystems. Countries that fail often lack one or more of these, or they try to do too much too quickly without building the ecosystem first.
