    Abstract: There is provided a method of filling a recess of a workpiece, which includes: forming a first thin film made of a semiconductor material along a wall surface defining a recess in a semiconductor substrate; annealing the workpiece within a vessel whose internal process is set to a first pressure, and forming an epitaxial region which is generated by crystallizing the semiconductor material of the first thin film, along a surface defining the recess, without moving the first thin film; forming a second thin film made of the semiconductor material along the wall surface defining the recess; and annealing the workpiece within the vessel whose internal pressure is set to a second pressure lower than the first pressure, and forming a further epitaxial region which is generated by crystallizing the semiconductor material of the second thin film which is moved toward a bottom of the recess.

    Abstract translation: 提供了填充工件的凹部的方法,其包括:沿着限定半导体衬底中的凹部的壁表面形成由半导体材料制成的第一薄膜; 在其内部工艺设定为第一压力的容器内对工件进行退火,以及形成沿着限定凹部的表面使第一薄膜的半导体材料结晶而不移动第一薄膜产生的外延区域; 沿着限定所述凹部的壁表面形成由所述半导体材料制成的第二薄膜; 以及将内部压力设定为低于第一压力的第二压力的容器内的工件退火,以及形成另外的外延区域,该外延区域通过使朝向凹部的底部移动的第二薄膜的半导体材料结晶而产生 。
