Semiconductors are materials which have a conductivity between conductors (general metals) and nonconductors or insulators (such as ceramics). Semiconductors are made from pure elements, typically silicon or germanium, or compounds such as gallium arsenide. In a process called doping, small amounts of impurities are added to pure semiconductors causing large changes in the conductivity of the material.
The process of manufacturing semiconductors or integrated circuits (commonly called ICs or chips) typically consists of hundreds of steps, during which hundreds of copies of an integrated circuit are formed on a single wafer.
Generally, the process involves the creation of 8 to 20, and frequently more, patterned layers on (and into) the wafer, ultimately forming the complete integrated circuit. This layering process creates (interconnected) electrically active regions on the semiconductor wafer surface (source: www.semiconductors.org).
SAT Group contributes to the production of semiconductors by manufacturing ultra high purity components and reliable wet bench systems. We offer manual, semi-automated, and fully automated wet benches that are fully customizable for a wide variety of configurations and processes.
