Abstract:
1. A substrate processing apparatus which laminates layers of resultants of at least two kinds of mutually reactive gases and forms a thin film on a surface of a substrate by performing a gas supply cycle to supply sequentially the reactive gases to the surface of the substrate in a vacuum chamber, the substrate processing apparatus comprising: a film deposition device to perform a film deposition process of the substrate; a vacuum conveying chamber airtightly connected to the film deposition device; a conveying unit disposed in the vacuum conveying chamber to convey the substrate between the film deposition device and the vacuum conveying chamber; a heat processing device including a processing container airtightly connected to the vacuum conveying chamber and including a substrate mounting base provided therein and a unit to perform heat processing of the substrate on the mounting base; a substrate rotating unit arranged in the vacuum conveying chamber or the heat processing device to cause the substrate on the conveying unit to rotate around a vertical axis of the substrate and to rotate with respect to the conveying unit; and a control unit to output a control signal so that a film deposition process of the substrate is carried out, the film deposition device comprising: a table arranged in the vacuum chamber; a plurality of reactive gas supplying units arranged to face an upper surface of the table and mutually separated in a circumferential direction of the table to supply the reactive gases to the surface of the substrate respectively; a separating gas supplying unit to supply a separating gas; an isolation area disposed between a plurality of processing areas to which the reactive gases are respectively supplied from the plurality of reactive gas supplying units, the separating gas being supplied from the separating gas supplying unit to the isolation area so that atmospheres of the plurality of processing areas are divided by the separating gas in the isolation area; a rotation device that rotates to perform a relative rotation between the plurality of reactive gas supplying units and the separating gas supplying unit with respect to the table around a vertical axis of the table; a substrate mounting area arranged in the table along a direction of rotation of the table so that the substrate located in the substrate mounting area is moved sequentially to the plurality of processing areas and the isolation area by the rotation of the rotation device; and an evacuation unit to perform evacuation of the inside of the vacuum chamber, wherein the control unit is configured to
