Claim 0:
1. A method for forming a silicon nitride film on at least one surface of a substrate by an atomic layer deposition process, the method comprising:
providing the at least one surface of the substrate in a reactor;
introducing into the reactor at least one halidosilane precursor from the group consisting of monochlorodisilane (MCDS), monobromodisilane (MBDS), monoiododisilane (MIDS), monochlorotrisilane (MCTS), monobromotrisilane (MBTS), and monoiodotrisilane (MITS), wherein the at least one halidosilane precursor is the only silicon-containing precursor introduced into the reactor, and
introducing a nitrogen-containing source into the reactor to form the silicon nitride film on the at least one surface.
