For semiconductor manufacturers, ultrapure water (UPW) is a critical utility. Maintaining high precision and product yield requires water purity that meets stringent specifications at every stage. For a major manufacturer in the US Upper Midwest, ensuring this level of purity is a core operational requirement.
The facility recently underwent a significant expansion to double its wafer production from 20,000 to 40,000 units per day. To support this growth, the company modernized the plant with updated instrumentation and automated systems. During this transition, METTLER TOLEDO Thornton identified a vital upgrade path for the facility’s aging sodium and silica analyzers.
The manufacturer had been using older competitor models that were increasingly difficult to maintain. Ready to move toward a more reliable, low-maintenance solution for their new process skid, they turned to Thornton. Based on a long-standing trust in METTLER TOLEDO’s performance, they selected a comprehensive suite of digital measurement tools tailored to their high-volume requirements.
The upgrade included a range of specialized analyzers and sensors:
The 2300Na and 2850Si analyzers provide constant, on-line monitoring of trace contaminants. Features like predictive diagnostics, adjustable cycles, and minimal reagent use allow operators to focus on production rather than constant equipment upkeep.
Thanks to METTLER TOLEDO’s Intelligent Sensor Management (ISM™) technology and ISM Core™ software, the customer benefits from seamless pH sensor calibration and maintenance away from the process line, realtime sensor health diagnostics, and electronic documentation— ensuring precision and reducing downtime.
Support and service
Beyond the hardware, METTLER TOLEDO Thornton provided a full service package, including installation, calibration, and preventative maintenance. A 24-month Extended Care Service contract ensures the manufacturer has the technical support needed for sustained long-term performance.
A proven industry partnership
In an environment where water quality directly impacts microelectronics yield, this project demonstrates how modern sensor technology stabilizes production. METTLER TOLEDO Thornton continues to provide the precision instruments required for high-stakes UPW monitoring and process integrity
