    Abstract: A method of growing a crystal in a recess in a substrate on which an insulating film having the recess is formed, includes: forming a first film on the insulating film at a thickness as not to completely fill the recess; etching the first film by an etching gas to remain the first film only in a bottom portion of the recess; annealing the substrate such that the first film in the bottom portion is modified into a crystalline layer; forming a second film on the insulating film and a surface of the crystalline layer at a thickness as not to completely fill the recess; annealing the substrate such that the second film is crystallized from the bottom portion through a solid phase epitaxial growth to form an epitaxial crystal layer; and etching and removing the second film remaining on the substrate by an etching gas.

    Abstract: A depression filling method for filling a depression of a workpiece including a semiconductor substrate and an insulating film formed on the semiconductor substrate is provided. The depression penetrating the insulating film is configured so as to extend to the semiconductor substrate. The method includes: forming a thin film of a semiconductor material along a wall surface that defines the depression; annealing the workpiece to cause the semiconductor material of the thin film to move toward a bottom of the depression and to form an epitaxial region corresponding to crystals of the semiconductor substrate; and etching the thin film.

    Abstract: A selective epitaxial growth method includes preparing a target object including a single crystal substrate in which an epitaxial growth region is partitioned by a suppression film; and growing the epitaxial layer on the epitaxial growth region of the target object until a predetermined film thickness is obtained. The growing the epitaxial layer includes first source gas supply process of supplying a source gas onto the target object under a first pressure to grow a first epitaxial layer on the epitaxial growth region, first removing process of removing deposits on the suppression film, second source gas supply process of supplying the source gas onto the target object under a second pressure higher than the first pressure, and second removing process of removing the deposits on the suppression film. The second source gas supply process and the second removing process are repeated until the predetermined film thickness is obtained.

    Abstract: There is provided a cleaning method of a substrate processing apparatus comprising cleaning an inside of an exhaust pipe through which a gas of an inside of a processing container is exhausted. The cleaning the inside of the exhaust pipe includes: removing a deposit on a downstream side of an opening/closing valve in the exhaust pipe by supplying a first exhaust pipe cleaning gas containing fluorine to the downstream side of the opening/closing valve in the exhaust pipe in a state in which the opening/closing valve provided in a middle of the exhaust pipe is closed; and removing a deposit on an upstream side of the opening/closing valve in the exhaust pipe by supplying a second exhaust pipe cleaning gas not containing fluorine as a gas constituent element to the inside of the processing container in a state in which the opening/closing valve is opened.
