Abstract :
Implementation of advanced control on a manufacturing tool requires the integration of several modules like performance specification, sensors, system models, and a control framework. This paper discusses the implementation of real-time process control and run-to-run process control on furnace chemical vapor deposition (CVD), rapid thermal processing (RTP), and chemical mechanical polishing (CMP). Results demonstrating throughput enhancement and tighter process tolerances are presented
