  • Patent number: 8987123
    Abstract: After the completion of the transport of a semiconductor wafer into a chamber, the flow rate of nitrogen gas supplied into the chamber is decreased. In this state, a preheating treatment and flash irradiation are performed. The flow rate of nitrogen gas supplied into the chamber is increased when the temperature of the front surface of the semiconductor wafer is decreased to become equal to the temperature of the back surface thereof after reaching its maximum temperature by the irradiation of the substrate with a flash of light. Thereafter, the supply flow rate of nitrogen gas is maintained at a constant value until the semiconductor wafer is transported out of the chamber. This achieves the reduction in particles deposited on the semiconductor wafer while suppressing adverse effects resulting from the nonuniform in-plane temperature distribution of the semiconductor wafer.

  • Publication number: 20140330442
    Abstract: A power supply curve matching one of the patterns of a demand curve stored in advance is created by combining power generation quantities of various power sources. An environmental load index to a supply quantity indicated by the supply curve is calculated based on environmental load information stored in advance. Next, reducible quantity information for each power consumption reduction characteristic of each consumer is stored in advance, a necessary reduction quantity to cause the supply curve to match a predetermined curve is calculated. A reducible supply quantity is calculated based on reducible quantity information, and a reducible index obtained by dividing the reducible supply quantity by the necessary reduction quantity is calculated. Next, the supply curve is adjusted until it is determined that both environmental load index and the reducible index are within respective certain ranges.

  • Publication number: 20140169772
    Abstract: A susceptor of a holding part for holding a semiconductor wafer includes a disc-shaped holding plate, an annular shaped guide ring, and a plurality of support pins. The guide ring has an inside diameter greater than the diameter of the semiconductor wafer and is installed on the peripheral portion of the top face of the holding plate. The guide ring has a tapered surface along the inner circumference. The semiconductor wafer before irradiated with flash light is supported by the support pins. The annular shape of the guide ring increases the contact area when the semiconductor wafer that has jumped off the susceptor and fallen when irradiated with flash light collides with the guide ring, thus reducing the impact of the collision and preventing cracks in the substrate.
