Abstract :
The aim of this study was to analyse the stress state in silicon dies joined by Low Temperature Joining Technology (LTJT) based on measurements and simulation results. The focus was to establish a method to determine the initial stress state and stress-free temperature in a silicon die attached to a copper substrate after the joining process. An approach to analyse the evolution of the stress state after sintering and during thermal cycling was developed.
