Micro-Raman spectroscopy, XRD, and analytical modelling are used to study stresses in and surrounding tungsten lines of different widths and spacing. The stress in the lines and in the adjacent substrate is calculated using a concentrated- and a distributed edge force model. Both models are adapted such that the substrate-stress components can also be calculated for an array of lines. The results from XRD and micro-Raman spectroscopy and the results from the distributed edge force model are in agreement. The combination of data from the two experimental techniques is shown to give some important feed-back to the theoretical models.
