摘要
Electron beam evaporation was employed to deposit hafnium on silicon (100) substrate, followed by a rapid thermal oxidation process to fabricate hafnium dioxide thin film. Hafnium was transformed to hafnium oxide above a oxidizing temperature of 500 T. An interfacial layer of hafnium silicate was observed between HfO2 and silicon substrate. Oxidation temperature greatly affects interfacial quality and leakage current of the film. (C) 2002 Published by Elsevier Science B.V.
