Semiconductor Fabs: Why the World Is Spending Trillions to Build More

The global chip shortage reminded everyone of something the industry already knew: when semiconductor manufacturing is concentrated in a handful of geographies, the entire electronics supply chain is exposed. Right now, ~75% of semiconductor manufacturing sits in China and East Asia – regions with documented seismic and geopolitical risk. The response has been a coordinated, trillion-dollar push to change that map.

The Expansion Wave

A 2024 Semiconductor Industry Association (SIA) report projects that US semiconductor output will more than triple between 2022 and 2032 – a growth rate exceeding 200%, against a projected global output increase of 108% over the same period.

That kind of growth doesn't come from optimising existing lines. It requires new high-volume fabs. As of December 2024, ~95 high-volume fabs had already been announced. Of these, 18 are expected to begin construction in 2025, with operations targeted for 2027. The US and Japan lead that pipeline, with four fabs each.

If the US targets are met – and existing leaders like China and Taiwan don't announce expansions of equivalent scale – the shift in global demand dynamics after 2032 could be substantial.

Inside a Fab: Precision at Nanometer Scale

To understand why this buildout matters, it helps to understand what a fab actually demands. Thousands of circuits are integrated onto wafers at thicknesses measured in nanometers. Every gas or chemical contacting the wafer surface must hold impurity levels below a few parts per billion (ppb). That's not a specification; it's the baseline.

Clean rooms maintain this environment through continuous circulation of particle-free air via HEPA and ULPA filters. Human access is strictly monitored. But beyond air quality, fabs rely on an infrastructure layer that rarely makes headlines: piping systems.

A single fab may require nearly 40 kilometres of pipelines just for ultra-pure water (UPW) transport. Beyond UPW, fabs use approximately 300 different chemical types, ~15% of which are toxic – plus large, continuous volumes of gases, including CO₂, nitrogen, and hydrogen. All of it requires leakproof, precisely engineered transport infrastructure throughout the facility.

The Demand Geography

Since fab locations drive piping demand, understanding capacity distribution is critical. According to our estimates, as of 2025:

• ~60% of global piping system demand from semiconductor fabs originates in the Asia-Pacific region
• China alone accounts for ~40% of that demand
• The US holds ~20% of global demand at current capacity

That last number is set to change significantly.

What This Means for the Supply Chain

The cumulative capital expenditure, spanning both private and government investments, during 2024–2032, is projected to exceed $2.3 trillion, with the majority (~60%) of this spending concentrated on Taiwan and the United States. Notable government initiatives and investments include China’s $142 bn equity funds, grants worth $39 billion under the U.S. CHIPS Act announced in August 2022, plus additional tax benefits.

In the private sector, some notable investments are TSMC’s $100 billion investment in the US, announced in March 2025, and Texas Instruments’ $60 billion investment in the US, announced in June 2025, among others.

With both demand and funding accelerating worldwide, the global semiconductor manufacturing market is projected to surpass $1 trillion by 2030. The corresponding demand for piping systems is estimated at over $720 million over the same period, according to Stratview Research. While this figure may appear modest compared to the trillion-dollar semiconductor market, it represents a substantial opportunity for specialized piping system providers to capitalize on.

The buildout creates compounding demand across a concentrated value chain: ultra-pure water systems, specialty gas delivery, chemical-handling pipelines, clean room infrastructure. Each new fab adds dozens of kilometres of system requirements. At 95+ fabs in the pipeline, the procurement scale is significant – and the window for suppliers to position themselves is now.
