Please Close the Loop

In the semiconductor clean room, the yellow light never goes out. After an engineer Zhang San made adjustments late at night, he discovered that his hardware colleague Xiao Li was kneeling next to the machine and then disappeared from all records. The company's report showed that Zhang San violated the two-person working standard that night and worked alone. In order to retrieve Xiao Li and prove that he is not crazy, Zhang San began to trace the anomalies in the clean room, but found that behind the yellow light, defect maps, daily reports and EHS procedures, there was something hidden that fed on "closed loops". It doesn't kill people. It will only make people normal, stable and compliant. Until everyone is part of the process.
