TSMC

in English: Taiwan Semiconductor Manufacturing Company

basicwidespread

TSMC is a Taiwanese chip manufacturing company that produces chips designed by others, including the vast majority of the most advanced processors powering artificial intelligence.

In plain terms

TSMC is like a giant printing press that does not write books itself but prints others' manuscripts, yet with such fine type that almost no one else can achieve it. Nvidia, Apple, or AMD design the chip, and TSMC manufactures it.

This arrangement is called contract manufacturing (the foundry model). Design companies thus do not need to build factories costing tens of billions of dollars, while TSMC can devote all its efforts to perfecting manufacturing.

It is a key player in AI because the vast majority of chips that train and run large language models come from its factories. If TSMC cannot produce more, the entire AI industry will grow more slowly, regardless of how much money is available.

Different from Intel or Samsung, because those companies also design and sell their own products. TSMC does not compete with its clients, so rivals are willing to entrust their most secret plans to it.

How it works

The client (for example, Nvidia) creates the chip blueprint and hands it over to TSMC. The design adheres to TSMC's pre-defined manufacturing rules.
In the factory, circuits are applied layer by layer with light onto clean silicon wafers. For the finest patterns, the Dutch company ASML uses special machines operating with extreme ultraviolet light.
Producing a wafer for the most advanced chips involves more than a thousand steps and takes months, in a dust-free environment known as a cleanroom. The smaller the transistors (for example, 3 or 2 nanometer technology), the faster and more energy-efficient the chip.
The finished wafer is sliced, and the chips are packaged. For AI chips, this is a particular bottleneck, because the processor and memory must be integrated into a single unit (this is called advanced packaging).
Finished chips go to the customer, who sells them under their own name. That is why you do not see the TSMC name on your phone or servers.

An everyday example

When you ask a question to an AI chatbot, the answer is generated in a data center on AI chips (mostly Nvidia chips), which were almost certainly manufactured by TSMC. The same applies to the processor in the phone in your pocket if you have an iPhone, and to most high-end Android devices.

Who is affected

everyoneYour phone, laptop, car, and most AI services you use run on TSMC chips, so the company's issues will appear in both prices and supply.

bank customer, investorTSMC is among the world's most valuable companies, and its orders reflect the state of the entire AI market, so many investment funds and pension savings include its shares. → Money

entrepreneur, executiveThe price and availability of AI services partly depend on how many chips TSMC can manufacture, which is worth considering in planning.

industrial worker, engineerThe automotive and machinery industries also depend on chip supply, as the 2021 chip shortage showed. → Industry

A common misconception

MythTSMC designs and devises the chips it manufactures.

In realityTSMC only manufactures: the designs are created by the clients (Nvidia, Apple, AMD and others). TSMC's expertise lies in its ability to implement these designs flawlessly and at scale.

Limits and risks

Most advanced manufacturing is concentrated in Taiwan, so an earthquake or escalating tensions with China could disrupt the global chip supply.
Capacity cannot be expanded quickly: building a new factory takes years and costs tens of billions of dollars, so sudden surges in AI demand can only be met with a delay.
TSMC itself depends on others, such as ASML's machines and suppliers of special chemicals, making the supply chain vulnerable at multiple points.
The nanometer figures appearing in the news (3 nm, 2 nm) are now more names of technology generations than actual dimensions, so they cannot be directly compared between manufacturers.

Similar, but not the same

Nvidia – Nvidia designs and sells AI chips but has no factory of its own; TSMC handles the manufacturing.
ASML – ASML produces the machines required for chip manufacturing; TSMC manufactures the chips themselves using these machines.
Intel – Intel traditionally designs and manufactures its own chips, while TSMC exclusively manufactures designs from others.

A brief history

TSMC was founded in Taiwan in 1987 by Morris Chang with support from the Taiwanese state. It was the first company built exclusively on contract manufacturing, meaning it did not design its own chips but only manufactured those of others.

Where things stand

At the end of 2026, TSMC is by far the largest player in manufacturing the most advanced chips and also uses 2-nanometer technology in mass production. It is expanding outside Taiwan, including in the United States, Japan and Germany, but most leading-edge production is still in Taiwan.
