Abstract
    Target Factor Analysis(TFA)is kind of mathematical technique for solving multidi-mensional problems of a certain type. By means of the technique,AES depth profiles of Ti/Al multi-film has been thoroughly studied in this paper. Each chemical state of Ti,Al,O, Si elements in depth distribution is obtained,and they were consistent with XPS analysis results.
