Abstract

TiAl based thin-films possess high oxidation-resistance and high meltingpoints, making them possible candidates for application in electronics. Thebehavior of the films upon exposure to various temperatures is of interestfor such application. In the present study, Ti37Al63thin films were deposited onto SiO2 substrates using RF magnetronsputtering from a compound target. Anneals were performed in vacuum attemperatures ranging from 400 °C to 700 °C. The phases and microstructuralbehavior of the films were evaluated as a function of annealing.Microstructural behavior was correlated with resistivity changes in thefilms. The behavior of Ti-Al films as potential under-layers for silvermetallization was also evaluated. The Ti-Al was observed to enhance thethermal stability of pure Al thin-films. The results are relevant forpotential application of the films to electronics.
