Event processing based system for manufacturing yield improvement

A non-transitory computer-readable storage medium having instructions encoded thereon that, when executed by a processing device, cause the processing device to perform operations comprising:

• identifying a process event associated with a defect known to potentially occur in a manufacturing process;
• selecting a plurality of data elements from a manufacturing data source based on the process event, wherein the manufacturing data source is associated with the manufacturing process during execution of the manufacturing process, and wherein selecting the plurality of data elements from the manufacturing data source comprises determining whether data to be utilized in applying an event rule associated with the process event is available in a real-time data stream, and in response to the determining:
• selecting a subset of the plurality of data elements from a historical data storage in response to determining that some of the data is unavailable in the real-time data stream;
• or selecting the plurality of data elements from the real-time data stream in response to determining that all of the data is available in the real-time data stream;
• during the execution of the manufacturing process, applying, by the processing device, an event rule to the plurality of data elements to determine whether the event rule is satisfied;
• during the execution of the manufacturing process, performing a predefined action upon determining that the event rule is satisfied, wherein the predefined action is performed before the defect occurs;
• and
• during the execution of the manufacturing process, selecting a plurality of additional data elements from the manufacturing data source based on the process event upon determining that the event rule is not satisfied;
• during the execution of the manufacturing process, receiving an updated or new event rule;
• and
• during the execution of the manufacturing process, applying the updated or new event rule to the plurality of data elements and historical data elements from the historical data storage.

A system comprising:

• a memory;
• and a processor communicatively coupled to the memory, wherein the processor is to:
• identify a process event associated with a defect known to potentially occur in a manufacturing process;
• select a plurality of data elements from a manufacturing data source based on the process event, wherein the manufacturing data source is associated with the manufacturing process during execution of the manufacturing process, and wherein to select the plurality of data elements from the manufacturing data source, the processing device is to further determine whether data to be utilized in applying an event rule associated with the process event is available in a real-time data stream, and in response to the determining:
• select a subset of the plurality of data elements from a historical data storage in response to determining that some of the data is unavailable in the real-time data stream;
• or select the plurality of data elements from the real-time data stream in response to determining that all of the data is available in the real-time data stream;
• during the execution of the manufacturing process, apply an event rule to the plurality of data elements to determine whether the event rule is satisfied;
• during the execution of the manufacturing process, perform a predefined action upon determining that the event rule is satisfied, wherein the action is performed before the defect occurs;
• during the execution of the manufacturing process, select a plurality of additional data elements from the manufacturing data source based on the process event upon determining that the event rule is not satisfied;
• during the execution of the manufacturing process, receiving an updated or new event rule;
• and during the execution of the manufacturing process, applying the updated or new event rule to the plurality of data elements and historical data elements from the historical data storage.
