  • Uncovering chemical quality improvements through a holistic approach to chemical quality management

    Abstract This paper focuses on a holistic approach to monitoring particles in ultra-pure chemicals from supplier all the way to the wafer surface. As critical dimensions shrink, this understanding will become very critical for cleaning equipment, processes, and the chemical delivery systems that supply them. Advancing technology in particle monitoring capabilities have made it possible to ...

  • By the Numbers

    In a sense, metrology makes the world go around. It can quantify how long it takes the Earth to rotate, and the science of weights and measurements underpins everything from telling time to ensuring the fairness of international trade agreements. Metrologists must be extremely precise in their measurements, according to Alan Steele, Canada’s chief metrologist and the general manager of ...

  • Keeping Healthcare/SPD Workers Safe from Exposure: 2 Very Different Options

    Continuous Monitoring vs. Badges Badges are designed to provide the Time Weighted Average (TWA) data for the total exposure period. They contain an absorption medium that reacts with or absorbs and holds the target chemical from the air to be analyzed later, which indicates the exposure after the fact. Badges, sample tubes, and wet chemical methods were the predominant technologies for monitoring ...
