摘要: 在以肼为还原剂的碱性化学镀镍溶液中实现p型单晶硅片上激光诱导微区化学沉镍,讨论了激光能量、照射时间对镍沉积层的影响。使用SEM、AES和RBS等方法对镀层的形貌、性质进行了分析。激光诱导化学沉积得到了均匀致密、结合力好的纯镍镀层。镀层与基体间具有Schottky接触特性。

Abstract: Selective deposition of thin nickel films on p-type silicon was obtained in a hy drazine-based conventional electroless nickel plating solution at the ambient temperature under laser irradiation.Composition and properties of the deposits were investigated using SEM,AESand RBStechniques.The deposits are in Schottky barrier contact with p-type silicon.The mechanism involved in the deposition process was also discussed.
