Vacuum Technology and Gas Delivery Systems

Students will explore the fundamental principles of vacuum physics, various vacuum pump technologies, and advanced metrology techniques for measuring ultra-high vacuum conditions. The course also covers the design, operation, and safety protocols associated with gas delivery systems, including inert, toxic, and corrosive gases. Graduates will be equipped to troubleshoot vacuum system failures, perform routine maintenance on pumps and gauges, and manage gas handling equipment in a semiconductor fabrication environment, ensuring process integrity and operational safety. This knowledge is essential for maintaining critical process parameters and preventing contamination.
