Patent number: 10612143Abstract: A raw material gas supply apparatus includes a raw material container, a carrier gas inlet line and a raw material gas line. The raw material container is configured to accommodate the solid raw material. The carrier gas inlet line is configured to discharge the carrier gas to the raw material gas originated from the solid raw material. The raw material gas is transferred to the consumption area together with the carrier gas through the raw material gas line. A flow rate of the carrier gas is set such that a variation rate of a gas flow rate of the raw material gas flowing in the raw material gas line obtained by subtracting a gas flow rate in the carrier gas inlet line from a gas flow rate in the raw material gas line becomes 10% or less.Type: GrantFiled: March 17, 2016Date of Patent: April 7, 2020Assignee: Tokyo Electron LimitedInventors: Eiichi Komori, Hironori Yagi

Patent number: 6473993Abstract: A semiconductor wafer is mounted on a susceptor disposed in a processing chamber, the wafer is heated at a temperature on the order of 1000° C. for annealing, and a gas is supplied from a gas supply device disposed opposite to the wafer. When raising the temperature of the wafer and/or when lowering the temperature of the wafer, intra-surface temperature difference is limited to a small value to suppress the occurrence of slips. A gas supply device is divided into sections corresponding to a central part and a peripheral part, respectively, of the wafer to supply the gas at different flow rates onto the central part and the peripheral part, respectively. When raising the temperature of the wafer, for example, a gas of a temperature higher (lower) than that of the wafer is supplied at a flow rate per unit area greater (lower) than that at which the gas is supplied to the peripheral part to the central part.Type: GrantFiled: March 30, 2000Date of Patent: November 5, 2002Assignee: Tokyo Electron LimitedInventors: Yasushi Yagi, Takeshi Sakuma, Wataru Okase, Masayuki Kitamura, Hironori Yagi, Eisuke Morisaki
