Abstract
A method for manufacturing a semiconductor device includes preparing a temporary fixing structure body in which semiconductor elements each including a first surface on which a connection terminal is formed and a second surface are attached to a temporary fixing material, forming a curable bonding adhesive layer on the second surface of each of the semiconductor elements, attaching a carrier to one surface of the curable bonding adhesive layer opposite to the semiconductor elements, fixing the semiconductor elements to the carrier by curing the curable bonding adhesive layer, and removing the temporary fixing material. The semiconductor elements are attached onto the temporary fixing material such that the first surface of each of the semiconductor elements is directed toward the temporary fixing material, and are encapsulated with an encapsulant material such that the second surface of each of the semiconductor elements is exposed from an encapsulant material layer.
