Modeling of Transient Heating in Smart Power Applications

  • L. Borucki


Economic forces and integrated product designs are forcing the fabrication of some smart power applications on smaller die and on alternative substrates. This results in greater heating for a given application. Thermal models of possible advanced versions of an automotive fuel injector application suggest that while steady state heating is acceptable in these designs, transient heating may become a concern. The peak transient temperature in a 50% shrink of the injector application would be close to the empirical safe design limit, while a reduced device on bonded wafers is predicted to exceed the limit. This requires consideration of innovative energy management strategies and careful reliability assessment.
