Data optimization in semiconductor manufacturing

In today´s fast paced world of automation and computers, collection of data is easier than ever. Unfortunately, data collection ease can frequently produce more data than is actually needed for good decision making. This proliferation of data collection can actually impede manufacturing efficiency. Data can be optimized in the sense that less data can be collected while actually getting better information. This paper gives an approach that was applied in reducing data collection in a modern semiconductor fab operation that was still ramping production. While data was reduced, information for decision making was improved. The approach is detailed step by step. A brief example of actual optimization activity is described
