Abstract:
1. A method for manufacturing a multilayered printed circuit board, comprising: forming a first insulating resin substrate comprising a resin insulating layer and a metal layer formed on a surface of the resin insulating layer and substantially corresponding to dimensions of a semiconductor device; forming on the surface of the resin insulating layer a second insulating resin substrate comprising a resin insulating layer such that a first surface of the metal layer is covered by the resin insulating layer of the second insulating resin substrate; forming a recess extending from an opposite surface of the resin insulating layer of the first insulating resin substrate to the metal layer of the first insulating resin substrate such that a second surface of the metal layer opposite to the first surface is exposed; accommodating the semiconductor device in the recess formed in the first insulating resin substrate such that the semiconductor device is mounted on the second surface of the metal layer; and forming a resin insulating layer on the opposite surface of the resin insulating layer of the first insulating resin substrate such that the semiconductor device accommodated in the recess in the first insulating resin substrate is covered by the resin insulating layer on the opposite surface of the resin insulating layer of the first insulating resin substrate.
