Abstract: a-C:H(N) films were deposited from mixture gases of C2H2, Ar and N2 by r.f.-d.c. PECVD method. The deposition process, structure and direct current resistivity of the a-C:H(N) films were studied. The deposition rate of the a-C:H(N)
films increases with the increase of C2H2 content in the feed gases. The study of XPS and FTIR spectroscopy indicates that up to 9.09at% N can be incorporated
with C atoms in a-C:H(N) films as C≡N and C--N. The bonded N in a-C:H(N) films leads to the decrease of direct current resistivity.

Key words: a-C:H(N) films, plasma enhanced chemical vapor deposition, deposition process, direct current resistivity
