Figure 4

Cross-sectional distributions of TiN 200FWHMδ(y, z)observed during the indentation with a load of 1.4N.
The local increase in out-of-plane FWHM90(y, z) (a) and in-plane FWHM0(y, z) (b) correlates well with the concentrations of out-of-plane and in-plane stress components σ22(y, z) and σ33(y, z) in Fig. 6. Different FWHM90(y, z) and FWHM0(y, z) in FUP and FLP regions demonstrate the presence of needle-like crystallite morphology as well as an abrupt change in the film microstructure at the FUP/FLP interface.
