The dimensions of semiconductors on the surface of a silicon wafer are typically measured in nanometers. Any foreign particle, no matter how small, can impair the function of the microchip. That is why the 100 or so individual steps to produce a microchip take place in a clean room environment.
When the wafers must be stored temporarily, they must likewise be kept under clean room conditions. This is where the CubeStocker from Fabmatics GmbH comes in. Based in Dresden, Germany, Fabmatics specializes in the transport, storage and handling of silicon wafers in semiconductor production. Founded in 1991, the company employs some 250 people. When designing the company’s equipment, engineers focus on precision, reliability and the elimination of particulates.
