Abstract

The structure of Ni(Pt)Si films was investigated using high-resolution electron microscopy (HREM), electron microdiffraction and image simulation techniques. Such films with 5 at. % Pt were sputter deposited onto (111) Si and annealed for l min at 500°C by rapid thermal annealing. Analysis of the HREM pictures, diffraction patterns, and simulation results has revealed that NiSi films containing Pt can assume both hexagonal and orthorhombic structures that can coexist in the same film. The presence of film stresses and Pt seems to play a role in the formation of hexagonal NiSi.
