Abstract :
The aim of this work is to compare two methods for the determination of thin films Young´s modulus and stress state: the bulge test and the point-deflection methods. The tested structures are silicon nitride and bilayers silicon nitride/silicon oxide membranes with thicknesses down to 100 nm. We report new experimental results for different shapes (square or rectangular) and dimensions.
