Abstract
A technique includes: (a) providing a substrate having a first surface and a second surface; (b) modifying the first surface to be terminated with a hydrocarbon group by supplying a hydrocarbon group-containing gas to the substrate; and (c) forming a film on the second surface by supplying a precursor and an oxygen- and hydrogen-containing gas to the substrate after modifying the first surface.
