 We have grown TiO2 and AlN under ultra high vacuum and high pressure conditions and studied their structures with using AES and SEM techniques. The obtained results show that an amorphous film of TiO2 and AlN could be formed on silicon substrate. Furthermore, TiO2 and AlN are high – K dielectric materials and they can thus be replaced to ultra thin gate oxide film.

Recently, high – K materials such as Al2O3 and TiO2 films have been studied to replace ultra thin gate silicon dioxide film. In the present work, these films were grown on the top of Si(100) surface at different temperatures and under ultra high vacuum conditions. The obtained results showed that Al2O3 has a structure better than that of TiO2 and thus can be used as a good gate dielectric ...
