Semiconductor Fab Cross-Section

1. Interstitial and fan deck (top level) The fan deck houses systems that keep the air in the clean room particle-free and precisely maintained at the right temperature and humidity for production. The interstitial is the tallest level of the fab. 2. Clean room level A clean room is made up of more than 1,200 factory tools that take pizza-size silicon wafers and eventually turn them into hundreds of computer chips. Clean room workers wear bunny suits to keep lint, hair and skin flakes off the wafers. Fun Fact Semiconductor fabs are usually lit with yellow lights. The yellow lighting is necessary in photolithography to prevent unwanted exposure of photoresist to light of shorter wavelengths. 3. Clean subfab level The clean subfab contains thousands of pumps, transformers, power cabinets and other systems that support the clean room. Large pipes called “laterals” carry gases, liquids, waste and exhaust to and from production tools. Workers don’t wear bunny suits here, but they do wear hard hats, safety glasses, gloves and shoe covers. 4. Utility level Electrical panels that support the fab are located here, along with the “mains” — large utility pipes and ductwork that feed up to the lateral pipes in the clean subfab. Also here are chiller and compressor systems. Workers who monitor the equipment on this level wear street clothes, hard hats and safety glasses.

An infographic shows a cutaway semiconductor fabrication facility divided into four stacked levels: the fan deck, clean room, clean subfab and utility level. The highly controlled air, yellow lighting, bunny suits, pipes and industrial machinery make ordinary chip manufacturing look like an elaborate supernatural ritual. It is shared as an absurd reaction to the idea that semiconductor fabs are much stranger and more mysterious than most people realize.
