contract manufacturer

in English: semiconductor foundry

advancedwidespread

A contract manufacturer is a chip factory that does not produce its own products but manufactures chips designed by other companies to order.

In plain terms

Imagine the printing press and the book publisher. The publisher edits and prepares the book for print but has no printing press of its own: it sends the finished material to a printer, which prints it. In the chip industry, the contract manufacturer is the printer, and the chip design company is the publisher.

This is necessary because building a modern chip factory costs tens of billions of dollars and must be renewed every few years. Most companies cannot afford this. Thus, designers specialize in design, and contract manufacturers in production.

From an AI perspective, this is a key issue: the vast majority of chips running chatbots and agents are made by a few contract manufacturers. If they lack free production capacity, no amount of money or ideas will yield enough chips.

How it works

The design company (such as Nvidia, AMD, or Apple) designs the chip and hands the final blueprint to the contract manufacturer.
The contract manufacturer sets the rules in advance: what can and cannot be produced with the given manufacturing technology. The design must adapt to this.
In the factory, chip patterns are applied to silicon wafers in hundreds of steps, or even over a thousand for the most advanced chips, layer by layer in dust-free cleanrooms. This process takes weeks, or months for the most cutting-edge chips.
The finished wafer is cut up, the chips are packaged and tested. This is often done by another company specialized in this, but the packaging of the most advanced AI chips is frequently handled by the contract manufacturer itself.
The client sells the chip under its own brand name. The contract manufacturer's name usually does not appear on the product.

An everyday example

When you read in the news that Nvidia cannot supply enough AI chips, the bottleneck is usually not at Nvidia, but at its suppliers: primarily the Taiwanese TSMC, which manufactures and packages the chips, and the memory chip manufacturers. The processor in your phone was most likely made by a contract manufacturer, not by the company whose name is on it.

Who is affected

everyoneYour phone, car, and the chips in the AI services you use depend on a few contract manufacturers, so a disruption there can reach you through price and supply changes.

bank customer, investorThe value of AI stocks largely depends on how much manufacturing capacity chip designers receive from contract manufacturers. → Money

industrial worker, engineerEuropean chip factory investments (such as the TSMC and partners' Dresden plant) are bringing new engineering and technician jobs, although several announced projects, including Intel's Magdeburg plant, have been cancelled. However, chip shortages can shut down entire production lines. → Industry

A common misconception

MythNvidia, Apple, or AMD manufacture their own chips.

In realityThese companies only design chips today, outsourcing manufacturing to foundries, mostly the Taiwanese TSMC. They do not have their own chip factories; AMD had one previously but spun it off in 2009 (which became the foundry GlobalFoundries).

Limits and risks

The production of the most advanced chips is concentrated in the hands of a few companies and largely in Taiwan, so an earthquake, power outage, or political crisis could disrupt the entire world's supply.
Manufacturing capacity cannot be expanded quickly: building and commissioning a new factory takes years.
Major clients compete for the most advanced production lines, while smaller companies often fall further back in the queue.
The term 'foundry' is also used in AI industry software product names, so always check in news whether it refers to a chip factory or software.

Similar, but not the same

fabless chip designer – A fabless company only designs and sells, while the contract manufacturer only produces: they are each other's clients and suppliers.
integrated device manufacturer (IDM) – An integrated manufacturer, traditionally such as Intel or Samsung, designs and manufactures its own chips. Today both companies also offer contract manufacturing for others.
Foundry software platforms – The Microsoft Foundry software platform is used to build AI applications and agents, while Palantir Foundry is an enterprise data management and analytics platform. Neither has any connection to chip manufacturing.

A brief history

The first pure-play contract chipmaker was Taiwan's TSMC, founded by Morris Chang in 1987. The English word "foundry" originally means a metal casting works, and the chip industry borrowed it from there.

Where things stand

Contract manufacturing is the foundational model of the chip industry; the vast majority of the most advanced AI chips are produced by TSMC, with Samsung and Intel trying to catch up. The United States, the EU and Japan are building their own manufacturing capacity with state support, but dependence on Taiwan remains strong at the end of 2026.
