Aluminium Oxide Evaporation technique
To evaporate thermally aluminium oxide it is required high temperatures to obtain reasonable deposition rates. Electron beam evaporation is preferred for depositing aluminium oxide films as the material is rated excellent for this method. It can be evaporated from a tungsten crucible liner or from the copper hearth.
