利用电子束蒸发制备高K介质TiO2薄膜
Preparation of high-k gate dielectric film TiO2 thin film via electron electron beam evaporation
摘要
Abstract
TiO2 films were fabricated by electron beam evaporation with different substrate temperatures and evaporation beams, and the refractive index and thickness were measured by ellipsometry.The capacitor properties were characterized by high frequency capacitance-voltage.The results show the substrate temperature and evaporation beam taking the important effect on the capacitor properties.The composition was characterized by XPS and FI--IR, and it is found that the TiO2 film contains substoichiometric TiOx(r<2) and SiOy(y<2) in the TiO2-Si interface.关键词
