Claim 0:
1. A method of manufacturing a semiconductor device, comprising:
forming an oxide film in which a first oxide film and a second oxide film are alternately laminated on a substrate by alternately performing, a predetermined number of times:
(a) forming the first oxide film containing an atom X by performing a first cycle n1 times (n1 is an integer of 1 or more), the first cycle including non-simultaneously performing (a1) forming a first layer including a component in which a first functional group is bonded to the atom X by supplying a precursor, which includes a partial structure in which the first functional group and a second functional group are directly bonded to the atom X and has a bonding energy between the first functional group and the atom X higher than a bonding energy between the second functional group and the atom X, to the substrate, and (a2) forming a second layer containing the atom X and oxygen by supplying a first oxidizing agent to the substrate to oxidize the first layer; and
(b) forming the second oxide film containing the atom X by performing a second cycle n2 times (n2 is an integer of 1 or more), the second cycle including non-simultaneously performing (b1) forming a third layer including a component in which the first functional group is bonded to the atom X by supplying the precursor to the substrate, and (b2) forming a fourth layer containing the atom X and oxygen by supplying a second oxidizing agent to the substrate to oxidize the third layer, under a processing condition that an oxidizing power is higher than an oxidizing power when oxidizing the first layer in (a2).
