ABSTRACTRapid grain growth has been induced in semiconductor films at relatively low temperatures by allowing contact with metals or metal/semiconductor eutectic melts. Mechanisms by which such enhanced grain growth can occur are discussed, and Diffusion Induced Boundary Migration has been shown to be a plausible explanation for the experimental observations from the Sn/Ge, Al/Ge and Au/Ge systems. Interface migration driven by the decrease in free energy during phase transformations however provides a better explanation of the large Si grains produced on heating the Au/Si samples.

Aluminum-copper-silicon thin films have been considered as an interconnection metallurgy for integrated circuit applications. Various schemes have been proposed to incorporate small percent-ages of silicon into films that typically contain two to five percent copper. We undertook a study of the total effect of silicon on the aluminum copper film as revealed by transmission electron microscopy, scanning electron microscopy, x-ray diffraction and ion microprobe techniques as a function of the various deposition methods.X-ray investigations noted a change in solid solution concentration as a function of Si content before and after heat-treatment. The amount of solid solution in the Al increased with heat-treatment for films with ≥2% silicon and decreased for films <2% silicon.

AbstractThin (<1000 Å) hydrogenated nanocrystalline silicon films are widely used in solar cells, light emitting diodes, and spatial light modulators. In this work the conductivity of doped and undoped amorphous-nanocrystalline silicon thin films is studied as a function of film thickness: a giant anisotropy of conductivity is established. The longitudinal conductivity decreases dramatically (by a factor of 109 − 1010) as the layer thickness is reduced from 1500 Å to 200 Å, while the transverse conductivity remains close to that of a doped a- Si:H. The data obtained are interpreted in terms of the percolation theory.
