Cima. Spee et al., DEPOSITION OF TITANIUM NITRIDE THIN-FILMS AT LOW-TEMPERATURES BY CVD USING METALORGANIC AND ORGANOMETALLIC TITANIUM COMPOUNDS AS PRECURSORS, Journal de physique. IV, 3(C3), 1993, pp. 289-296
A series of titanium compounds, Ti(NMe2)4, t-BuTi(NMe2)3, [Ti(mu-N-t-B
u)(-NMe2)2]2, Ti(t-BuDAD)2 and CpTiC7H7, have been screened in combina
tion with NH3 for their suitability as precursors for the CVD of titan
ium nitride films at substrate temperatures of 300-600-degrees-C and a
system pressure ot 1.5 Torr. The best TiN layers have been grown usin
g t-BuTi(NMe2)3 and NH3, from which an 0.8 mum thick layer deposited a
t 400-degrees-C, showed a resistivity of 1.4 . 10(-3) OMEGA . cm and c
ontained 5 atom% carbon and 6 atom% oxygen.
