Abstract:
1. A process tool optimization system for process tools that process substrates, comprising: a memory to store end-of-line yield data, and at least one processor, coupled to the memory, to execute: an end-of-line data mining engine that to analyze the end-of-line yield data, and to identify one or more process tools and time periods associated with low yield; a process tool data mining engine to identify the one or more process tools associated with the low yield from the end-of-line data mining engine, to obtain process tool data from the identified one or more process tools in correlation with the data received from the end-of-line data mining engine, to analyze constantly during processing of the substratesthe process tool data from the identified one or more process tools, and to identify one or more process tool parameters associated with the low yield based on the analyzing and the data received from the end-of-line data mining engine; and a data collection tool to monitor process control parameters of one or more process tools, and to transmit one or more of the process tool data and an analysis of the process tool data to the process tool data mining engine, wherein the analysis is based on one or more models of expected tool behavior.
