    摘要: In a method for manufacturing a semiconductor device, including forming an insulator film including a material having Si—CH3 bond and Si—OH bond, and irradiating the insulator film with ultraviolet rays, the rate of decrease of C concentration by X-ray photoelectron spectroscopy is not more than 30%, and the rate of decrease of one or more bonds selected from the group consisting of C—H bond, O—H bond and Si—O bond of Si—OH is not less than 10%, as a result of ultraviolet ray irradiation. A low-dielectric-constant insulator film that has a high film strength and can prevent increase of dielectric constant due to moisture absorption, a semiconductor device that can prevent device response speed delay and reliability decrease due to parasite capacity increase, and a manufacturing method therefor are provided.
