Serving the global semiconductor wafertest / waferprobe and IATF-16949 R&D community with traceable, ISO9001:2015 and ISO/IEC 17025:2017 accredited temperature calibration, calibration wafers and thermal chuck / wafer prober calibrations
Sigma Sensors provides the semiconductor industry with calibration solutions that ensure precision, accuracy, and compliance with international standards
Precision RTD Temperature Calibration Wafers
The SigmaTek Calibration Wafer System integrates with the prober and/or chuck controller to enable fully automated, operator-free temperature calibration with statistical analysis and reporting. Our systems can be ISO9001:2015 ISO/IEC 17025:2017 accredited calibrated and are traceable to the international standard. Featuring low-drift PT-100 4-wire sensors, the Cowboy / Calibration Wafer achieves sensor-to-sensor accuracy < 0.03°C and absolute accuracy up to +-0.1°K (0.2K, k=2), and is available in 150mm, 200mm, and 300mm sizes with up to 29 sensors.
On-site Prober Calibration
Sigma Sensors offers on-site thermal chuck / prober calibration services within the EU, US and SE Asia, using the SigmaTek Calibration Wafer system. The system holds an accredited ISO/IEC 17025 calibration with traceability to ITS-90, allowing you to document your compliance to international standards. Our technicians can calibrate multiple probers in parallel, and work around your schedule. Minimizing tool down-time and task-switching within your engineering team. Also available: remote calibration.
Temperature Wafer Calibration
We calibrate any RTD and TC temperature calibation wafer, including 3rd party such as KLA Tencor Sensarray and others from -75°C to +300°C. We offer fast turnaround times of less than 1 week on our ISO/IEC 17025 accredited calibration services. For each calibration performed, we issue a traceable or ISO/IEC 17025:2017 accredited calibration certificate, depending on your requirements.
Turn your broken third party wafer into a working SigmaTek system for roughly the cost of recalibration. You have a prober or other tool you want to trade? We are interested to hear from you.
