The manufacturing process of wafers requires the use of ultra-high purity gases. In this miniature process, the smallest impurities can cause major damages in a wafer and hence, cause imperfection, waste and avoidable costs. Many precautions can be taken by the manufacturer to expect a optimal level of impurity. Among them, requesting strict gas specifications from suppliers, using many purification techniques and monitoring in real-time the gas purity in the manufacturing process.
KaInstruments offers semiconductor manufacturers analyzers and systems that continuously monitor their process gases prior to entering the wafer manufacturing process.
