About this opportunity
BACKGROUND Semiconductor manufacturing yield enhancement requires ongoing risk analysis of cleaning chemical purity wherein critical contaminants are already at levels difficult or impossible to detect, let alone identify and quantify. Next-generation chips will require even purer materials and advanced metrological capabilities for the detection, identification, and quantification of impurities in semiconductor cleaning chemicals, necessitating a practical roadmap for assessing material purity commensurate with the needs of the next generation in semiconductor manufacturing. The purification of water to ultrapure water is a critical process in various semiconductor and research applications, where even trace amounts of contaminants at the parts-per-billion level (ppb, 10-9 moles per mole)...
