| Abstract: | The surface temperature and body temperature distribution of power FET are measured and analyzed by means of micro-thermal video system and numerical modelling respectively.The surface emissivity and environment radiation coefficient are calibrated. The thermal contact resistances of material interfaces are taken into consideration and found playing an important role on chip temperature rise through three dimensional static numerical modelling. |

| Keywords: | thermal image thermal reliability numerical modelling thermal contact resistance. |
