Si wafer temperature measurement
WebbThe thermistor is to monitor the reference temperature of the environment (−25–120 °C), which is critical for calibrating the devices' temperature drifts. Such a “4-in-1” composite sensor can be employed in buildings and traffic facilities for environment monitoring, hazard warning and security management. Webbetry, which cannot be used in the low-temperature regime (O-400 “C) because of the transparency of the Si wafers in the IR. In the literature a few methods have been sug- …
