【Abstract】 It is very important for formation of PtSi thin film to make the phases of thin film change into Pt\-2Si and PtSi. The formation process of phases is observed by X\|ray diffraction (XRD) and X\|ray photo spectrum (XPS), and the effects on the formation mechanism of phases of sputtering PtSi thin film are discussed, which annealed in different conditions, i.e. long time non isothermal annealing, vacuum annealing and vacuum annealing under protecting gas(H\-2 and N\-2). The research results show that annealed in protecting gas of H\-2 can improve quality of PtSi thin film evidently, and vacuum annealing may decrease the effect of oxygen on formation phases of PtSi thin film.更多还原
