Case Study: a North American semiconductor manufacturer prevents pump downtime with Nanoprecise Sci Corp's predictive maintenance

a North American semiconductor manufacturer prevents pump failure with Nanoprecise

A North American semiconductor manufacturer faced the challenge of maintaining hundreds of mechanical dry and vacuum pumps critical to its subfab processes. Any pump degradation risked vacuum instability, contamination, and costly unplanned downtime, which could severely impact wafer yield. To address this operational risk, the manufacturer deployed Nanoprecise’s predictive maintenance solution, leveraging their MachineDoctor™ IoT sensors to gain continuous visibility into asset health and enable proactive maintenance.

The solution involved installing Nanoprecise's IIoT sensors on key equipment to monitor vibration and other parameters. This allowed for the early detection of mechanical degradation in a two-stage vacuum pump through advanced analytics. Nanoprecise's system alerted the maintenance team, who confirmed internal damage and scheduled a controlled replacement. This proactive approach prevented process disruptions, potential wafer scrap, and unplanned downtime, improving maintenance planning and reducing operational risk for the manufacturer.
