It does not address how these systems will be applied to solve problems, nor does it address other contributors to process variations such as thermal wafer processing, exposure tool focus control, materials, etc.\u003c\/p\u003e \u003cp dir=\"ltr\" align=\"justify\"\u003e \u003c\/p\u003e \u003cp dir=\"ltr\" align=\"justify\"\u003eThis document discusses determining the performance of gauging\/measurement systems for a very specific application—the lithography section of integrated circuit wafer fabrication. This document in many cases, will be applicable to IC mask-making, in which case the word \"mask\" can be substituted for \"wafer.\"\u003c\/p\u003e \u003cp dir=\"ltr\" align=\"justify\"\u003e　\u003c\/p\u003e \u003cp dir=\"ltr\" align=\"justify\"\u003eIt is acknowledged that the final measurement for a fabricated wafer is the electrical functionality. However, the intermediate lithographic measurements can be useful in prediction and control of final functionality. This document is intended to be useful for this litho-metrology application, irrespective of the technology employed.\u003c\/p\u003e \u003cp dir=\"ltr\" align=\"justify\"\u003e　\u003c\/p\u003e \u003cp dir=\"ltr\" align=\"justify\"\u003eMeasurement results and system performance depend on the sample(s) used.
