  • Publication number: 20080241384
    Abstract: A deposition apparatus and deposition method for forming a film on a substrate are disclosed. A film is deposited on a substrate by exposing the substrate to different flow directions of reactant gases. In one embodiment, the substrate is rotated in the reaction chamber after a film having an intermediate thickness is formed on the substrate. In other embodiments, the substrate is transferred from one reaction chamber to another after a film having an intermediate thickness is formed on the substrate. Accordingly, a film having a uniform thickness is deposited, averaging out depletion effect.

  • Publication number: 20080069955
    Abstract: The present invention relates to an ALD apparatus, and particularly relates to an ALD apparatus that is suitable for rapidly depositing a thin film on a substrate having an actual area that is larger than a planar substrate. In the reaction chamber of the ALD apparatus according to an exemplary embodiment of the present invention, more gas is supplied to a portion where more gas is required by having differences in the space for gas to flow rather than supplying the gas in a constant flux and a constant flow velocity such that the time required for supplying reactant gases and waste of reactant gases may be minimized to increase productivity of the ALD apparatus. The ceiling of the reaction space is shaped to provide a nonuniform gap over the substrate.

  • Publication number: 20070215036
    Abstract: Space and time co-divided atomic layer deposition (ALD) apparatuses and methods are provided. Substrates are moved (e.g., rotated) among multiple reaction zones, each of which is exposed to only one ALD reactant. At the same time, reactants are pulsed in each reaction zone, with purging or other gas removal methods between pulses. Separate exhaust passages for each reactant and purging during wafer movement minimizes particle contamination. Additionally, preferred embodiments permit different pulsing times in each reaction space, thus permitting flexibility in pulsing.

  • Publication number: 20070190782
    Abstract: A ruthenium film deposition method is disclosed. In one embodiment of the method, a first ruthenium film is deposited by using a PEALD process until a substrate is substantially entirely covered with the first ruthenium film. Then, a second ruthenium film is deposited on the first ruthenium film by using a thermal ALD process having a higher deposition speed than that of the PEALD process. In the method, a ruthenium metal film having a high density is formed in a short time by combining a PEALD process of depositing a ruthenium film at a low deposition speed and a deposition process of depositing a ruthenium film at a higher deposition speed. Accordingly, it is possible to form a ruthenium film having high density, a smooth surface, good adhesiveness, and a short incubation period.
