Introduction :
A semiconductor fab, short for “fabrication facility,” is a specialized manufacturing plant where semiconductor devices, such as integrated circuits (ICs), microchips, and other electronic components, are designed, manufactured, and assembled.
These facilities are essential for the production of the electronic components that power modern technology.
In a semiconductor fab, the fabrication process involves multiple intricate steps to create semiconductor devices from raw materials, typically silicon wafers.
These wafers go through a sequence of processes, including deposition of various materials, photolithography (a technique for creating patterns on wafers), etching, doping (adding impurities to modify conductivity), and more.
These steps are repeated multiple times to build complex structures on the wafers, ultimately forming the integrated circuits that make up electronic devices.
Semiconductor fabs require controlled environments, often referred to as “clean rooms,” to minimize contamination that could negatively impact the delicate manufacturing process.
The air in these clean rooms is filtered and regulated to prevent dust, particles, and other impurities from interfering with the manufacturing process.
Semiconductor fabs play a crucial role in advancing technology by enabling the production of smaller, faster, and more efficient electronic components that power everything from smartphones and computers to automobiles and medical devices.
