The object of the present invention is to provide a laminate having a low relative dielectric constant and exhibiting excellent adhesion, a method of forming the laminate, an insulating film, a semiconductor device, and a film-forming composition are provided. A laminate according to the invention includes: a first silica-based film; a second silica-based film; and an organic film, wherein the second silica-based film includes a monovalent organic group containing a carbon-carbon double bond or a carbon-carbon triple bond. A method of forming a laminate according to the invention includes: forming a first coating for a first silica-based film on a substrate; forming a second coating for a second silica-based film on the first coating, the second coating including a monovalent organic group containing a carbon-carbon double bond or a carbon-carbon triple bond; forming a third coating for an organic film on the second coating; and curing a multilayer film including the first to third coatings. |
