选择外延
Therefore ALE is also called "digital epitaxy". In comparison with conventional MBE and MOCVD, ALE offers advantages of greater thickness uniformity, fewer surface defects, less edge growth in selective epitaxy and monolayer control in sidewall epitaxy.
与传统的MBE和MOCVD相比,ALE具有生长层厚度更均匀、缺陷密度更低、选择外廷中无边缘生长以及侧壁外延可控制到单原子层等优点。
