The practice of digital twinship in semiconductor testing equipment

Abstract： Digital twin is an essential technology in smart manufacturing and has practical value in factories. At a semiconductor testing services company, a digital twin system was used to collect over 200 000 alarm data points from probe stations. The analysis showed that more than 90% of the alarms were resolved remotely using the digital twin system. To improve the digital twin model and alarm management, alarms were replicated within the model by simulating different scenarios. Operating the digital twin system manually reduced equipment downtime by over 64% compared to traditional methods. Additionally, using an AI backend to automatically operate the digital twin system further reduced equipment waiting time by 78%. This highlights the importance of personnel response time to equipment alarms in affecting equipment downtime. Therefore, enhancing the use of digital twin models for automated alarm handling can significantly reduce equipment downtime and improve overall equipment utilization.
