Abstract

The effect of oxygen incorporation on the growth and microstructure of TiSi2 has been investigated. Cosputtered films, with Si/Ti ratios between one and three, were deposited on (100) Si substrates and reacted at temperatures from 650° to 1050°C. Both Auger electron spectroscopy, in conjunction with sputter profiling, and Rutherford backscattering spectrometry indicate that oxygen in the as-deposited films redistributes to the silicide-silicon interface upon heating. Cross sectional transmission electron microscope images show that the oxygen is present as an amorphous oxide.
