A look at cleanroom manufacturing Source: Adobe Stock Any foreign particle is a disruption Why are the requirements so stringent? On a microchip the size thickness of the connecting structures is one thousandth of the diameter of a human hair. This means that a foreign particle of any size can ruin a chip and reduce yield. Given the extreme cost of these production plants, even very small particle ingress can make the entire production uneconomical. of a fingernail, there is room for several billion transistors, and the This shows that cleanroom requirements for abrasion resistance are extreme and cannot be fulfilled with normal moving components. are the typical requirements of energy supply systems for semiconductor manufacture. igus ® has developed a new application for this concept that has been well-received in microchip manufacture (especially in East Asia), and is suitable for hygienic food production. Abrasion-free, hygienic, flexible, high availability - these Main text to ISO 14644-1, in which components such as semiconductors are manufactured? By themselves, the numbers (per cubic meter, there may be no more than 400 particles that are between 0.5 and 1µm) do not communicate much. To make them meaningful, we need a comparison. One cubic meter of city air contains between 15 and 100 million particles of various sizes, and clean mountain air contains 10 million particles per cubic meter. In one cubic meter of air next to a smoker, there are up to 100 million particles larger than 0.5µm. How pure is the air in a cleanroom that is classification 1 according
