The same Digital Twin serves as the base for FPS applications at all installations. With nearly a hundred distinct and diverse facilities currently using the Digital Twin, INFICON strives to solve client requests always in a general, rather than a site-specific way. As a result, the Data Warehouse is a repository of industry knowledge and best practices. It computes and stores a large array of useful and value added quantities that many clients do not think to ask about but are delighted when they discover them in the system. Besides key features like Enhanced Tool Performance states, Enhanced Cycle Time, and Throughput, there are smaller statistics like transit times, lot ships, line balance quantities, test wafer data, and more. When a new factory installs the FPS Digital Twin, that facility obtains solutions to problems and requests from more than two decades of diverse end user feedback.
