Claim 15:
16. The method of claim 2, wherein processing conditions in (b-1) satisfy at least one of following conditions (1) to (5):
(1) a pressure of a processing chamber is set to a smaller value than that of a pressure at which an adsorption of the first reactant to an entire surface of the recess in a depth direction of the recess is completed,
(2) a processing time is set to be shorter than a processing time for which the adsorption of the first reactant to the entire surface of the recess in the depth direction of the recess is completed,
(3) a dilution degree of the first reactant is set to a higher value than that of a dilution degree at which the adsorption of the first reactant to the entire surface of the recess in the depth direction of the recess is completed,
(4) a temperature of a stage disposed the substrate is set to be lower than a temperature at which the adsorption of the first reactant to the entire surface of the recess in the depth direction of the recess is completed, and
(5) a plasma is generated in (b-1), and an absolute value of a radio-frequency (RF) power applied for generating plasma is set to be smaller than an absolute value at which the adsorption of the first reactant to the entire surface of the recess in the depth direction of the recess is completed.
