Abstract
Based on 3D FEM electro-thermal simulations, we explore the thermal impact of source metallization ageing inducing a bonding wire lift off on a VDMOS device. This kind of failure is usually modeled by changing the geometry of the assembly, without considering the physical properties evolution of aged materials such as the source metallization. This work aims to highlight the importance of taking into account material evolution due to ageing in 3D FEM electro-thermal simulations.
