Abstract

A method for producing a semiconductor device, including forming a temporary fixing laminated body including a carrier, and a sealing structure body provided on a main surface of the carrier, and removing the carrier from the temporary fixing laminated body. The temporary fixing laminated body is formed by a method including adhering the curable resin film and the carrier. The carrier is removed from the temporary fixing laminated body by separating a protective layer that is the curable resin film that is cured from the carrier. The curable resin film exhibits a transmittance of 20% or less with respect to light at a wavelength of 355 nm when cured.
