The Ue methodology and system is a powerful breakthrough in providing direct feedback to the tool owners. It captures the essence of measuring what is possible and helps to achieve operational excellence. This system has been in development and implementation for the last three years at Intel and has shown significant results and improvements. It can be used to drive operational execution to a new level, and since it is easily portable to multiple tools, it can be leveraged in the constant moving constraints of the factory. The potential benefits can be overwhelming if applied correctly. The methodology used for Ue can be easily used in any fab, sort, or assembly facility, given, of course, that the appropriate data are available. The Ue indicator is currently being used across multiple Intel 300-mm and 200-mm factories and is in the process of proliferation to the remaining facilities
