The Implementation of SEMI E176: Guide to Assessing and Minimizing Electromagnetic Interference in a Semiconductor Manufacturing Environment

inCompliance Magazine

An article by Intel, Applied Materials, and OnFILTER outlining basic steps for compliance with SEMI E176 Standard on reducing and managing electromagnetic interference in semiconductor manufacturing and handling.  


Electromagnetic interference is a significant contributor to latent failure of devices in the field and yield, as well as process variations, equipment interruption and malfunction.  Following SEMI E176 guidance on managing EMI and limiting EMI levels in process as recommended by SEMI E176 facilitates error-free operation, reduction of variables and higher reliability of devices.  


Presentation on SEMI EMC Standards

IEEE EMC Symposium

EMC Standards are very important for the industry - they help to reduce downtime, improve productivity and yield by controlling EMI levels in the environment.  Semiconductor industry has specific requirements that are not addressed by "generic" EMC regulations, among them actual EMI levels in the factory, transient, not just continuous signals, EMI inside critical process equipment and others.  Vladimir Kraz of OnFILTER who leads SEMI EMC Standards' Task Force presented a paper at the 2019 IEEE EMC Symposium introducing IEEE EMC Society to SEMI EMC Standards and its specific requirements.  If you are interested in the actual paper contact Vladimir at
