Abstract:
1. A film deposition apparatus configured to deposit a film on a substrate, the film deposition apparatus comprising: a vacuum container having a transfer opening; a table disposed in the vacuum container, on which a substrate loaded into the vacuum container via the transfer opening can be placed; a process-gas supply part disposed in an upper part of the vacuum container so as to be opposed to the table, and configured to supply a process gas to the substrate placed on the table; an elevating mechanism configured to vertically move the table between a process position at which the substrate is subjected to a film deposition process, and a transfer position at which the substrate is transferred to and from an external transfer mechanism that has entered from the transfer opening; a surrounding part configured to surround the table with a gap therebetween, when the table is located at the process position, so that the surrounding part and the table divide an inside of the vacuum container into an upper space, which is located above the table, and a lower space, which is located below the table; a vacuum exhaust conduit having an exhaust duct disposed along a circumference of the upper space and having an exhaust port through which a process atmosphere in the upper space is discharged to create a vacuum in the upper space; a purge-gas supply conduit configured to supply a purge gas into the lower space so that the purge gas flows into the upper space via the gap between the table and the surrounding part; a heating unit configured to heat a gas contact region ranging from the upper space to the vacuum exhaust conduit, to a temperature higher than a temperature allowing adhesion of reactant; and a heat insulation part disposed between the heating unit and a lower part of the vacuum container.
