This thesis is a study of copper thin film on an alumina substrate in order to realize passive components operating at high temperature. A study of copper thin films was made by simulation using COMSOL Multiphysics software and experimentally using specific characterization benches. This study highlighted an increase of Von Mises equivalent stresses with temperature and with copper thickness. Simulations also show a relaxation of residual stresses after one hour of annealing. Experimental results show an increase of adhesion in function of temperature and an absence of cracks. On the other hand, electrical studies for integrated components were performed either after annealing or in thermal cycling (25-200°C). These measures highlighted ind...
