Abstract

Dysprosium oxide (Dy₂O₃) deposited by MBF on n-Si (100) was investigated. The electrical characteristics of the films seemed to depend on the annealing process after deposition. In the case of ex-situ O ₂ RTA for 5 min, the accumulation capacitance in the C-V characteristic decreased by the interfacial layer growth. On the other hands, it was found that excellent C-V characteristics without decrease of accumulation capacitance were obtained by in-situ vacuum anneal.
