    摘要: A vertical heat treatment apparatus includes: a substrate holder including a column, substrate holding parts configured to hold the substrates, and gas flow guide parts installed in the column in a corresponding relationship with the substrates; an elevator stand configured to support the substrate holder and to load the substrate holder into the reaction vessel from below the reaction vessel; a rotating mechanism installed in the elevator stand and configured to rotate the substrate holder about a vertical axis; a process gas supply port and an exhaust port respectively formed at a rear side and a front side of a substrate holding region; and a plurality of baffle parts installed independently of the substrate holder so that the baffle parts protrude from the outside toward spaces between the gas flow guide parts adjoining each other and run into the spaces.

    摘要: A processing apparatus includes: a processing container having a substantially cylindrical shape; a gas nozzle extending in a longitudinal direction of the processing container along an inside of a side wall of the processing container; an exhaust body formed on the side wall on an opposite side of the processing container to face the processing gas nozzle; and an adjustment gas nozzle configured to eject a concentration adjustment gas toward a center of the processing container. The adjustment gas nozzle is provided within an angle range in which the exhaust body is formed at a central angle with reference to the center of the processing container in a plan view from the longitudinal direction.

    摘要: A method of filling a depression of a workpiece is provided. The method includes forming a first thin film made of a semiconductor material substantially not containing an impurity along a wall surface which defines the depression, forming an epitaxial region conforming to crystals of the semiconductor substrate from the semiconductor material of the first thin film moved toward a bottom of the depression by annealing, etching the first thin film remaining on the wall surface, performing gas phase doping upon the epitaxial region, forming a second thin film made of a semiconductor material substantially not containing an impurity along the wall surface, further forming an epitaxial region from the semiconductor material of the second thin film moved toward the bottom of the depression by annealing, and performing gas phase doping upon the second thin film remaining on the wall surface and the epitaxial region.
