Beyond HEPAs: Practical Applications of Assessment, Control, and Monitoring for AMC in Microelectronics Manufacturing Applications

In this course attendees will learn the practical aspects of airborne molecular contamination (AMC) control in cleanrooms, with an emphasis on applications for the microelectronics industry. A three-step Assessment, Control, and Monitoring program for the optimum control of AMC will be presented and discussed. Examples of successful AMC control applications will be provided to illustrate the design concepts discussed and their impact on the final choice of systems.
