Abstract:
1. A method of manufacturing a semiconductor element mounted wiring board, comprising: preparing a metal plate with an opening portion formed therein and then attaching the metal plate to a surface of a support base member; mounting a semiconductor element on the surface of the support base member in a face-up position, the surface of the support base member corresponding to the opening portion of the metal plate; forming an insulating layer so as to cover the metal plate and the semiconductor element on the support base member and thereby fabricating a semiconductor element sealed substrate; fabricating a wiring substrate by stacking wiring layers and insulating layers on a temporary substrate, and forming a conductive bump on the outermost wiring layer; stacking the semiconductor element sealed substrate and the wiring substrate on each other in such a way that an electrode terminal of the semiconductor element and the corresponding conductive bump on the outermost wiring layer face each other, and then connecting the electrode terminal to the conductive bump; and removing the support base member and the temporary substrate.
