摘要

The ultra-thin HfO2/SiO2 gate stack high-k dielectrics were deposited by atomic layer deposition. The physical and structural properties of the HfO2/SiO2 films were investigated. Atomic force microscopy, transmission electron microscopy and X-ray reflectivity analysis results indicate that the atomic layer deposition can deposit HfO2/SiO2 gate stack dielectrics with good performance.
