Patent ID: 8460470

Claim:
A vapor phase deposition apparatus comprising: a chamber; a support table arranged in the chamber, and having a first support unit which is in contact with only a peripheral portion of a back side surface of a substrate and on which the substrate is placed and a second support unit which is connected to the first support unit to support the first support unit, a material used in the first support unit having a heat conductivity higher than that of a material used in the second support unit, wherein the first support unit and the second support unit are configured to rotate when a vapor phase deposition is performed for the substrate, notched portions are formed on an upper surface side of the first support unit and an upper surface side of the second support unit at a position which the first support unit and the second support unit are connected to each other, and a space is formed by the notched portion of the first support unit and the notched portion of the second support unit at the position which the first support unit and the second support unit are connected to each other; a first heat source arranged at a position having a distance from a back side surface of the substrate, the distance being larger than a distance between back side surface of the support table and the first heat source, and which heats an outer peripheral portion of the substrate and the first and second support units; a second heat source arranged under the first heat source, so that a portion of the second heat source overlaps with the first heat source and a remaining portion of the second heat source does not overlap with the first heat source, and which heats all remaining portions of the back side surface of the substrate except for the outer peripheral portion of the substrate, not through the first heat source and the first and second support units; a first flow path configured to supply a gas to form a film into the chamber; and a second flow path configured to exhaust the gas from the chamber, wherein the first support unit and the second support unit are configured to rotate independently from the first and the second heat sources, and the apparatus has a single wafer type system.
