Patent ID: 7777328

Claim:
A substrate comprising: an inorganic material base board having a recess and at least one first penetration hole provided around the recess; a semiconductor device accommodated in the recess and including at least one electrode pad provided on a surface of the semiconductor device; resin filling provided in the at least one first penetration hole; a plurality of second penetration holes formed in the resin filling in the at least one first penetration hole so as to penetrate the resin filling; a plurality of through-holes including the plurality of second penetration holes and conductive material provided in the plurality of second penetration holes, and electrically connecting conductive wirings provided on a top surface and a back surface of the inorganic material base board; and an insulating layer which covers the surface of the semiconductor device, a surface of the resin filling, and a surface of the inorganic material base board and which has a first opening corresponding to the plurality of through-holes and a second opening corresponding to the at least one electrode pad; wherein the conductive wiring formed on a surface of the insulating layer for electrically connecting the plurality of through-holes and the at least one electrode pad, and wherein the plurality of through-holes is formed in the resin filling provided in the at least one first penetration hole.
