The invention includes methods of forming a conductive silicide layers on silicon comprising substrates, and methods of forming conductive silicide contacts. In one implementation, a method of forming a conductive silicide layer on a silicon comprising substrate includes reacting oxygen with silicon of a silicon comprising substrate to form oxides of silicon from silicon of the substrate. The oxides of silicon include stoichiometric silicon dioxide and substoichiometric silicon dioxide. The stoichiometric silicon dioxide and substoichiometric silicon dioxide are exposed to ozone to transform at least some of the substoichiometric silicon dioxide to stoichiometric silicon dioxide. After the exposing, a conductive metal silicide is formed in electrical connection with silicon of the silicon comprising substrate.
