Abstract:
A method for depositing multiple layers of titanium-based film onto a substrate by sequential chemical vapor deposition (CVD), comprising the steps of introducing a substrate and a source precursor into a CVD chamber, wherein the source precursor is a vapor of at least one compound of formula (I):Ti(I.sub.4-m-n)(Br.sub.m)(Cl.sub.n) (I)wherein m is 0-4 and n is 0-2; and sequentially depositing onto the substrate at a temperature of about 200-650.degree. C. layers of titanium metal film and titanium nitride film, wherein either the titanium metal film or the titanium nitride film may be deposited first onto the substrate and wherein at least the titanium metal film is deposited in the presence of a plasma, with hydrogen halides or ammonium halides being major byproducts of the deposition.
