Some embodiments include methods of titanium deposition in which a silicon-containing surface and an electrically insulative surface are both exposed to titanium-containing material, and in which such exposure forms titanium suicide from the silicon-containing surface while not depositing titanium onto the electrically insulative surface. The embodiments may include atomic layer deposition processes, and may include a hydrogen pre-treatment of the silicon-containing surfaces to activate the surfaces for reaction with the titanium-containing material. Some embodiments include methods of titanium deposition in which a semiconductor material surface and an electrically insulative surface are both exposed to titanium-containing material, and in which a titanium-containing film is uniformly deposited across both surfaces.
