摘要

Texture, microstructure and stresses were investigated in 0.18 μm damascene Cu interconnect lines. Additionally, for purpose of comparison, the same parameters were investigated in 0.25 μm, 2 μm damascene Cu lines and Cu blanket film. Measurements were done using x-ray diffraction (XRD) and orientation imaging microscopy (OIM). Both macro and microtexture were characterized by computing the orientation distribution functions (ODFs) and inverse pole figures. Microstructure was characterized by computing - unique grain color maps, mean grain size and coincident site lattice (CSV) boundary distribution. Stresses were measured by XRD using sin~2ψ method.
