Abstract: Improved process control systems may include shared safety control and process control components/elements, facilitating the sharing of sensors, actuators, and input/output (I/O) interface circuitry between the safety functionality of the system and the general operational (i.e. normal) functionality of the system. Components and/or circuitry corresponding to safety operations of the system may be designed to permit inputs to be monitored during normal operations at all times as there is typically no safety risk associated with monitoring. The components and/or circuitry corresponding (or dedicated) to the safety operations of the system may operate to prevent normal operational control of various designated outputs/actuators when there is a need to activate safety functions. When there is no need to activate safety functions, these same components and/or circuitry may allow normal operational control of the designated outputs/actuators.

Abstract: In a lithographic process in which a series of substrates are processed in different contexts, object data (such as performance data representing overlay measured on a set of substrates that have been processed previously) is received. Context data represents one or more parameters of the lithographic process that vary between substrates within the set. By principal component analysis or other statistical analysis of the performance data, the set of substrates are partitioned into two or more subsets. The first partitioning of the substrates and the context data are used to identify one or more relevant context parameters, being parameters of the lithographic process that are observed to correlate most strongly with the first partitioning. The lithographic apparatus is controlled for new substrates by reference to the identified relevant context parameters. Embodiments with feedback control and feedforward control are described.
