The Critical Role of Fresh Air in Semiconductor Manufacturing
Semiconductor fabrication plants, or "fabs," require massive amounts of fresh air primarily to maintain an ultra-clean, tightly controlled environment that is essential for producing microchips. This process is incredibly sensitive, and the tiniest particle or fluctuation in conditions can ruin an entire batch of wafers. The Role of Fresh Air in Cleanrooms The HVAC system in a semiconductor fab is not just for comfort; it is a critical part of the manufacturing process. Fresh, outside air, known as makeup air , is brought into the fab and undergoes an extensive purification process. It's the foundation of a sophisticated air management system designed to achieve three main goals: contamination control, pressure regulation, and environmental stability. Contamination Control : This is the most crucial reason. Semiconductor manufacturing deals with features on a scale of nanometers, making them extremely vulnerable to even microscopic contaminants. The fresh air is first ...
