摘要: 将电子束蒸发在硅衬底(P型,〈100〉晶向,0-5 Ω·cm) 上厚度400 nm 、纯度99-99 %的铝膜,浸入具有中等溶解能力的15 wt% H2SO4 中,DC恒压60 V、恒温0 ℃条件下,进行多孔型过度阳极氧化处理,从而在Si 基上得到包含空隙层的多孔氧化铝膜.通过对样品TEM 平面形貌、SEM 横断面形貌观察以及AES深度剖析,研究了样品的多层结构,并初步讨论了由此揭示出的硅基多孔氧化铝膜的生长过程

Abstract: nm aluminum films were deposited onto a p_type,0.5 Ω·cm, 〈100〉 oriented silicon wafers using electron beam evaporation technique.Then,the wafers was immersed in 15 wt% H 2SO 4 for porous_type over_anodization under a constant voltage of DC 60V.During the anodization,the temperature of the electrolyte was maintained at 0 ℃.The obtained samples were investigated by means of transmission electron microscopy,scanning electron microscopy,and AES depth profile for multi_layer structural information.In addition, the basic anodic formation mechanism of the Si_based aluminum films was brielfly discussed.

Key words: Anodic oxidation, Si_based porous alumina, AES, Multi_layer structure
