A recovery process of a damaged layer and a reducing process of an oxide are performed on a substrate in which the oxide and the damaged layer from which carbon has been eliminated are formed on exposed surfaces of a Cu wiring and a SiCOH film as a low-k film, respectively. In the same processing chamber 51, a recovery process of a damaged layer 15 and a reducing process of an oxide/fluoride layer 16 are performed on a wafer W in which the damaged layer 15 from which carbon has been eliminated and the oxide/fluoride layer 16 are formed on exposed surfaces of an interlayer insulating film 4 containing SiCOH and a wiring 2 containing Cu, respectively, by consecutively supplying H2 gas and TMSDMA gas containing silicon and carbon in sequence.
