A method of depositing a silicon film on a recess formed in a surface of a substrate is provided. The substrate is placed on a rotary table in a vacuum vessel, so as to pass through first, second, and third processing regions in the vacuum vessel. An interior of the vacuum vessel is set to a first temperature capable of breaking an Si—H bond. In the first processing region, Si2H6 gas having a temperature less than the first temperature is supplied to form an SiH3 molecular layer on its surface. In the second processing region, a silicon atomic layer is exposed on the surface of the substrate, by breaking the Si—H bond in the SiH3 molecular layer. In the third processing region, by anisotropic etching, the silicon atomic layer on an upper portion of an inner wall of the recess is selectively removed.
