Abstract
A manufacturing method for a semiconductor device includes generating on a substrate liquid-phase silanol having fluidity by causing a source gas made of a material containing silicon to react with a source gas made of a material containing oxygen, introducing the silanol into a first recess having an aspect ratio of a predetermined value wholly, and introducing the silanol into a space from a bottom to an intermediate portion in a second recess having an aspect ratio lower than the predetermined value, the first and second recesses are provided in the substrate, burying a silicon oxide film in the first recess and providing the silicon oxide film in the second recess by converting the silanol into the silicon oxide film by dehydrating condensation, and providing a dielectric film having film density higher than that of the silicon oxide film on the silicon oxide film.
