Abstract:
An apparatus for depositing a thin film using remote plasma, in which a first reactive gas and a second reactive gas is fed with the aid of a carrier gas into a vacuum chamber, said apparatus comprising:a plurality of transfer pipes interconnected with a plurality of valves for individually transferring the first and the second reactive gas and the carrier gas to the vacuum chamber, said plurality of transfer pipes comprising a first pipe line carrying said first reactive gas to said vacuum chamber and a second pipe line carrying a second reactive gas to said vacuum chamber, said first pipe line being separated from said second pipe line; an energy supplier, provided inside the plurality of transfer pipes, said energy supplier supplying excitation energy to generate excited plasma to ionize the first reactive gas prior to introduction of said first reactive gas into said vacuum chamber; and a valve controller controlling said plurality of valves established in the transfer pipes, the controller being programmed and configured to alternately feed into the vacuum chamber the second reactive gas and the first reactive gas ionized to said plasma at predetermined time intervals.
