Serving the global semiconductor industry with ISO/IEC 17025:2017 accredited and ITS90 traceable thermal calibrations – thermal chucks, calibration wafers for surface temperature measurement as well as burn-in ovens, freezers, environmental enclosures, liquid baths, dryblocks and temperature measuring systems.
At Sigma Sensors we strive to provide our customers the highest quality service to internationally established standards. Our goal is to be an instrumental partner to our customers in meeting their calibration requirements and to exceed expectations by continual improvement.
ISO/IEC 17025:2017 is the global standard for calibration laboratories. We offer traceable, accurate, and precise temperature measurements for the semiconductor industry globally as well as standard thermometer and temperature sensor calibration services.
Sigma Sensors TCL is the first and only temperature calibration laboratory specializing in surface temperature measurement for wafertest globally. Our focused area of expertise are thermal chuck and temperature wafer calibrations along with burn-in ovens, freezers, oil and liquid baths, dryblocks and other environmental enclosures. In short: anything related to temperature.
When temperature counts and traceability to ITS90 is required, you can count on us – where measurements are performed with confidence in the results: Sigma Sensors.
Our presence on three continents (Europe, North America, Asia) ensures global reach and convenience.
Calibrated sensors have inherently improved accuracy specifications over DIN spec sensors as seen in the graph. The colored graphs depict uncertainty as per accuracy class specification.
At 200 degrees Celsius these range from ±0.5C° to ±2.5C° compared to a calibrated sensor whose accuracy can be as low as ±0.03 to 0.05K°, K=2. This makes a SiGMA K2 sensor more accurate by a factor of 10.
Our calibrated sensors get installed in the COWBOY WAFER, a <4mm Si wafer sandwich. Physical contact
is optimized and outside influences minimized. This enables us to accurately measure the temperature of
the wafer and therefore get a picture of the temperature distribution of the thermal chuck.
Our COWBOY Wafer comes as a complete, rugged, easy to use temperature calibration system. The case integrated cataloguers are hardwired to the wafer interface cable above the electronics compartment is the wafer storage. The notched wafer gets places ib the tgenrak chuck, the cables get plugged into the corresponding wafer tails. The USB out end of from the case gets plugged into the computer and the system is ready for acquiring live data.
Contact us with your calibration needs, and we will ensure to give you a tailored solution.
