FCC metal thin films are often deposited with a strong (111) texture, but under relatively mild annealing conditions, the texture may transform into the much more compliant (100) orientation. This transformation dramatically changes film properties and can therefore be problematic for potential applications. Although the texture transformation is well known to depend on thickness, the few studies in which temperature dependence have been examined suggest that there is little or no effect of increasing annealing temperature up to agglomeration. To investigate this, Ag films were annealed at temperatures from 100 to 500˚C and the texture transformation was monitored with x-ray diffraction. Surprisingly, films annealed at low temperatures or under slowly increasing temperature ramps, transformed more than identical films annealed at higher temperatures. A variety of phenomena, including grain boundary grooving, are discussed as possible explanations for this behavior, with the eventual goal of being able to stabilize a desired microstructure.
