摘要	The interfacial properties of high-k dielectric CaZrOx thin films deposited by pulsed laser deposition in O-2 and N-2 ambient are investigated. The SiOx (x < 2) interfacial layer is observed for the films deposited at 300 degrees C in 20 Pa O-2. Rapid thermal annealing (RTA) of the films at 700 degrees C in N-2 for 10 s allows for oxidization of the interfacial layers into SiO2 and decomposition of the films into nano-ZrO2 crystals embedded in the matrix of amorphous CaO-rich zirconate. However, by the same RTA, the films deposited at 300 degrees C in 20 Pa N-2 remain amorphous with clean Si/CaZrOx interface and exhibit good electrical performances.
