What Are Semiconductor Fabs?
Semiconductor foundries i.e Fab are specialised manufacturing facilities that produce semiconductor devices on a large scale. These facilities are equipped with the advanced technology and expertise required to fabricate integrated circuits (ICs) and other electronic components.
By outsourcing semiconductor production to foundries, companies can focus on designing innovative chips without the need to invest in their own costly manufacturing facilities. This allows for greater flexibility and efficiency in the semiconductor industry, driving advancements in technology across various sectors.

A real life Analogy
A semiconductor fab, short for semiconductor fabrication facility, is essentially a highly specialized factory where semiconductor devices like microchips or integrated circuits are manufactured on a large scale. Let’s explain this using an analogy involving a bakery.
Imagine a semiconductor fab as a high-tech bakery. In a bakery, various ingredients like flour, sugar, eggs, and yeast are combined in specific ways to create different types of baked goods like bread, cakes, and cookies. Similarly, in a semiconductor fab, raw materials (e.g., silicon wafers, chemicals, metals) are used in precise processes to create semiconductor devices like transistors, diodes, and memory cells.
Ingredients (Raw Materials):- Design Companies
- In a bakery: Flour, sugar, eggs, etc.
- In a semiconductor fab: Silicon wafers, chemicals, metals, etc.
Recipe (Manufacturing Process):- Foundries
- In a bakery: Specific recipes and techniques to make different baked goods.
- In a semiconductor fab: Precise manufacturing processes (like photolithography, etching, doping) to create different semiconductor components.
Baking Process (Fabrication Process):
- In a bakery: Baking at precise temperatures and times to create the final product.
- In a semiconductor fab: Precise conditions, temperatures, and steps in the fabrication process to create functioning semiconductor devices.
Final Products (Semiconductor Devices):- Testing and Packaging.
- In a bakery: Bread, cakes, cookies, etc.
- In a semiconductor fab: Microchips, integrated circuits, transistors, etc.
Just as a bakery requires careful control of ingredients, recipes, and baking processes to produce the desired baked goods, a semiconductor fab requires meticulous control of raw materials and manufacturing processes to produce precise and functional semiconductor devices.
