Nonlinear thermal effects in thin-film conductors on insulating substrates

Research output: Contribution to journalArticlepeer-review


A transmission-line treatment of heat flow in thin-film electric conductors on insulating substrates has confirmed that the temperature dependence of parameters such as metal resistance as well as metal and insulator specific heat and thermal conductivity should be included in any reliable model. The co-operative contribution of these nonlinearities determines the maximum temperature-time relationships. The results have important consequences for substrate electric fuses and for the transient ratings of silicon power devices.
