A Method for In-Situ, Total Ionising Dose Measurement of Temperature Coefficients of Semiconductor Device Parameters

This work presents and discusses a test method developed to allow the measurement of total ionising dose induced changes in temperature effects on electronic devices for space and nuclear applications. Two demonstration experiments testing commercial PMOS transistors were performed, using different methods of I-V curve measurement. The temperature of the devices during irradiation was controlled precisely using a commercial thermoelectric cooler. A programmable temperature controller combining digital and analogue control techniques was developed for this project. The experimental results allow better insight into the field of temperature sensitivity of PMOS devices.
