Summary

Sarah Vote, Director of Engineering at Entegris, delivers a seminar on contamination control in semiconductor manufacturing. She begins with her career path, highlighting her background in environmental chemistry and her transition to the semiconductor industry. She then introduces Entegris, a major supplier of materials and equipment for chip fabrication, emphasizing its role in providing purification solutions. The core of the talk focuses on the importance of contamination control: contaminants can be particles, metals, or gas-phase impurities, and they cause defects that significantly reduce yield. She explains that as feature sizes shrink, the tolerance for contamination becomes extremely stringent, and defect density has a larger impact on yield for larger chips. She also discusses the challenges of measuring and controlling impurities at parts-per-billion levels, and the need for collaboration between suppliers and fabs. Finally, she touches on gas purification systems, which are her specialty, and the importance of reliability and environmental considerations.
