2. METHODS AND MATERIALS Silicide formation was studied in Cr/a-Si thin film samples by Auger Electron Spectroscopy, X-ray Diffraction and in situ Transmission Electron Microscopy (AES, XRD, and TEM methods, respectively). The samples had a configuration of Cr/a-Si/c-Si for the AES and XRD measurements, while for the TEM measurements the configuration was Cr/a-Si/cleaved NaC1. The a-Si was produced either from a glow discharge in Sill4 *This research was supported in part by a grant from the National Council for Research and Developement, Israel, and the Forschungszentrum, Juelich, Germany.

N2 - Heat treatments in vacuum of Cr/a-Si:H, F structures lead to silicide formation at 450-600C. The presence of F in a-Si promotes the Cr silicide formation. The composition of the Cr silicides was found to depend on the relative thickness of the Cr and a-Si films. In the early stages of phase formation in the 400Å Cr/500Å a-Si system, with an atomic ratio of about 1:1 the first phases to appear were CrSi or CrSi2, then other silicide phases, Cr5Si3, and Cr3Si appeared. In the system with 1500Å Cr/1μm a-Si, with a surplus of Si, the dominant first phase was CrSi2, and then Cr3Si and Cr5Si3 appeared.
