## Abstract Al~2~O~3~ films 1 to 20 nm thick were deposited as alternative highβΞΊ gate dielectric on hydrogenβterminated silicon by Atomic Layer Deposition (ALD) and characterized by Synchrotron Xβray Photoelectron Specβtroscopy (SXPS), Fourier Transform Infrared (FTIR) absorption spectroscopy and
A1203-films deposited by atomic layer epitaxy onto silicon wafers were investigated structurally and electrically. A post-deposition anneal at 900Β°C resulted in a decrease in film thickness of about 10% and an increase in the index of refraction of about 3%. The densification did not significantly i
