A method for forming a metal thin film is suitable for suppressing the deterioration of a throughput according to enlarging a purge time to prevent the metal precursor from mixing with a reaction gas in a reactor during the deposition of an atomic layer. The method includes the steps of flowing a reaction gas into a reactor loaded therein a substrate, flowing a metal precursor in a pulse form into the reactor, activating the reaction gas by exiting a plasma in a pulse form to change with a pulse of the metal precursor in the reactor, alternately and depositing a metal thin film in a unit of an atomic layer by reacting the activated reaction gas with the metal precursor.
