Abstract
A foundation portion and a conductive base portion disposed on the foundation portion are formed on a temporary support, a semiconductor element electrically connected to the base portion is disposed on a side of the temporary support on which the foundation portion and the base portion are formed, and an insulating layer coming into a state of burying the foundation portion, the base portion, and the semiconductor element is formed on the temporary support. Subsequently, surfaces of the foundation portion and the insulating layer on a side of the temporary support are exposed by removing the temporary support, and the exposed foundation portion is further removed, thereby disposing the base portion in a state of being more recessed than the surface of the insulating layer. An external connection terminal is formed on the exposed base portion to manufacture the semiconductor package.
