A theoretical and experimental investigation on the electron impact ionization in silicon has been carried out in a temperature range up to about 1000 K. The proposed impact-ionization model amply extends the range of simulation tools up to temperatures which are important to predict the failure threshold of ESD-protection and power devices. Different protection diodes are investigated with electro-thermal simulation and transient interferometric thermal-mapping experiments in a new complementary approach. The prediction capability of the simulation tool is validated up to the thermal failure of the p-n junction. The temperature distribution and its dynamics during the application of high-current pulses are studied by comparing the calculated and experimental optical phase shifts: a quantitative agreement both in temporal evolution and thermal distribution is obtained up to temperatures of the order of 1000 K. ©2007 American Institute of Physics
