Abstract:
A carbon film containing fluorine and hydrogen, whereina spectrum determined by FT-IR (Fourier Transform Infrared) spectrum analysis exhibits such a relationship that a ratio (IR.Câ€”F)/(IR.Câ€”H) between a peak area (IR.Câ€”F) in a range from 1000 cmâˆ’1-1300 cmâˆ’1 resulting from Câ€”F bonds and a peak area IR.Câ€”H) in a range from 2800 cmâˆ’1 to 3100 cmâˆ’1 resulting from Câ€”H bonds is larger than 0, and a spectrum determined by XPS (X-ray photoelectron spectrum analysis) exhibits such a relationship that a ratio (F1S/C1S) between a peak intensity resulting from F1S and a peak intensity resulting from C1S is larger than 0 and smaller than 3; and wherein a rate of the Câ€”F bonds increases or decreases continuously or stepwise in the direction of the thickness of the film.
