Claim:
1. A method of processing a substrate having an insulating film and a conductive film, which are exposed on a surface of the substrate, comprising: selectively growing a laminated film on the conductive film by alternately performing a predetermined of times: wherein the conductive film contains at least one selected from a group consisting of a metal element, a semi-metal element, and a semiconductor element, wherein in the act of selectively growing the laminated film, the act of growing the first layer is performed before the act of growing the second layer, and the first layer and the second layer are laminated to form the laminated film, wherein the first element is antimony, the second element is tellurium, and the third element is germanium, wherein, when the act of growing the first layer is performed for the first time, the first layer is selectively grown on the conductive film, and when the act of growing the second layer is performed for the first time, the second layer is selectively grown on the first layer, and wherein the act of selectively growing the laminated film includes growing the laminated film as a superlattice by adjusting a thickness of the laminated film, a ratio of the first precursor and the second precursor, and a ratio of the second precursor and the third precursor.
