Abstract
A method for manufacturing 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 including a plurality of semiconductor chips and a sealing portion sealing the plurality of semiconductor chips, and removing the carrier from the temporary fixing laminated body. The semiconductor chip includes a chip main body including a first surface and a second surface, and a connection terminal provided on the first surface. The sealing portion includes an integrated protective layer adjacent to the carrier in the temporary fixing laminated body, covering the second surface. The protective layer is a cured curable resin film. The protective layer and the carrier are separated by irradiating the temporary fixing laminated body with incoherent light to remove the carrier from the temporary fixing laminated body.
