Mass analyzers are systems designed to identify and measure materials according to their molecular weights. The technique has been adapted for many other applications ranging from physics research and the identification of complex molecular structure to assuring the integrity of the fuel systems on the space shuttle and routine helium leak detection. While the uses of mass analyzers in the microelectronics industry include some exotic applications, such as SIMS, the greatest number of systems are used for various types of gas analysis. Applications for mass analyzers include process monitoring, process engineering and control in such areas as evaporation, MBE, sputter etch and deposition, plasma etch and deposition, ion, implantation, LPCVD, CVD, and diffusion furnaces. Another important application is high purity gas certification and electronic gas mixture verification.  2, record 1, English, - mass%20analyser
