In the highly complex world of semiconductor manufacturing vast amounts of largely varied data are generated every day. ASML, world-leader manufacturer of machines for the production of semiconductors (chips), is implementing a central data lake to capture this data and make it accessible for reporting and analytics in a central environment. The data lake environment also includes an analytics lab for detailed exploration of data. Managing all this rapidly changing data imposes some very challenging requirements. In this session, real-life examples of how ASML approaches these challenges are presented.
