  • Patent number: 11289344
    Abstract: When a carrier storing a plurality of dummy wafers therein is transported into a heat treatment apparatus, the carrier is registered as a dummy carrier exclusive to the dummy wafers. A dummy database in which a treatment history of each of the dummy wafers is associated with the carrier is held in a storage part. The treatment history of each of the dummy wafers registered in the dummy database is displayed on a display part of the heat treatment apparatus. An operator of the heat treatment apparatus views the displayed information to thereby appropriately grasp and manage the treatment history of each of the dummy wafers.

  • Patent number: 11183403
    Abstract: A semiconductor wafer held by a susceptor in a chamber is irradiated with halogen light radiated from a plurality of halogen lamps to be heated. A stainless steel block having an opening in a cylindrical shape is provided between the chamber and the halogen lamps. This reduces a distance from a light emitting portion in a light source region in which the plurality of halogen lamps is arranged, throughout the entire circumference of the opening in a cylindrical shape, so that the amount of reflected light from the inner wall surface of the opening toward the peripheral portion of the semiconductor wafer becomes uniform. This causes a uniform increase in illuminance of the peripheral portion of the semiconductor wafer, where temperature tends to decrease, at the time of light irradiation from the halogen lamps, so that in-plane temperature distribution of the semiconductor wafer can be made uniform.

  • Patent number: 11089657
    Abstract: A semiconductor wafer held by a holding part in a chamber is irradiated and heated with halogen light emitted from a plurality of halogen lamps. A cylindrical louver and an annular light-shielding member, both made of opaque quartz, are provided between the halogen lamps and the semiconductor wafer. The outer diameter of the light-shielding member is smaller than the inner diameter of the louver. Light emitted from the halogen lamps and passing through a clearance between the inner wall surface of the louver and the outer circumference of the light-shielding member is applied to a peripheral portion of the semiconductor wafer where a temperature drop is likely to occur. On the other hand, light travelling toward an overheat region that has a higher temperature than the other region and appears in the surface of the semiconductor wafer when only a louver is installed is blocked off by the light-shielding member.
