Chemical Vapor Deposition

• Deposition can also take place due to a chemical reaction between some reactants on the substrate. • In this case reactant gases (precursors) are pumped in to a reaction chamber (reactor). • Under the right conditions (T, P), they undergo a reaction at the substrate. • One of the products of the reaction gets deposited on the substrate.
