Key Differences
A fab, short for fabrication plant, is a highly specialized facility designed to manufacture integrated circuits and other semiconductor devices. On the other hand, a foundry, in the context of semiconductor manufacturing, is a type of fab that produces chips on behalf of other companies, which do not have their own manufacturing capabilities.
Fabs are typically owned and operated by companies that design and manufacture their own products, such as Intel and Samsung. Whereas foundries like TSMC and GlobalFoundries provide manufacturing services to fabless companies, which focus on chip design and leave the production to these third-party factories.
The investment in a fab is substantial, often running into billions of dollars due to the complex, clean room environments and sophisticated equipment required. On the other hand, foundries amortize their investment across multiple clients, potentially reducing the cost per chip for these clients due to economies of scale.
Fabs are equipped to handle the entire production process of semiconductors, from wafer fabrication to assembly and testing. In contrast, foundries might specialize in certain processes and offer varying levels of integration services based on client needs.
Fabs often drive technological innovation by developing new manufacturing technologies to stay competitive. Meanwhile, foundries must balance innovation with the diverse needs of their clients, focusing on flexibility and rapid scalability.

Common Curiosities
What is the primary function of a fab?
The primary function of a fab is to manufacture semiconductor devices for the company that owns it.
What are the advantages of using a foundry instead of building your own fab?
Using a foundry can significantly reduce capital expenditure and allow companies to leverage the foundry's expertise in mass production and technology.
How does a foundry differ from a traditional manufacturing facility?
Unlike traditional manufacturing facilities, a foundry specifically produces semiconductor chips on behalf of other companies, usually those without their own manufacturing capabilities.
Can a fab also act as a foundry?
Yes, some fabs like Samsung do both, manufacturing their own products and offering excess manufacturing capacity to other companies.
How do fabs and foundries contribute to technological advancements?
Fabs often develop proprietary manufacturing technologies that advance the overall field, while foundries must quickly adapt to and implement broad technological trends to meet client demands.
What industries rely on fabs and foundries?
Industries such as consumer electronics, computing, automotive, and telecommunications rely heavily on fabs and foundries for their semiconductor needs.
What is the role of a fab in product development?
A fab plays a critical role in product development by closely integrating design and manufacturing to streamline the production of semiconductor devices.
What is the investment difference between a fab and a foundry?
A fab requires a higher initial investment focused on a single company's needs, while a foundry's costs are distributed among various clients, potentially lowering the cost per unit.
What economies of scale can be achieved in a foundry?
Foundries achieve economies of scale by manufacturing large volumes of products for multiple clients, reducing the cost per unit through efficient use of resources and technology.
Why might a company choose to outsource to a foundry?
Outsourcing to a foundry allows companies to avoid the high costs of fab infrastructure and focus on design and innovation without the complexities of manufacturing.
Can the production quality differ between a fab and a foundry?
Production quality can vary; fabs might have tighter control over quality for their specific products, while foundries must meet a broad range of quality standards for various clients.
What strategic advantages do fabs offer to companies with high product demand?
For companies with high product demand, owning a fab ensures a steady supply of components, critical for maintaining market position and meeting consumer expectations.
What is the impact of a foundry's technological flexibility on its clients?
A foundry's technological flexibility can greatly benefit its clients by enabling them to adopt the latest technologies without personal investment in new equipment.
