Abstract:
1. A semiconductor device, comprising: a plurality of electronic components, each of which has at least one electrode; a plurality of wiring boards, each of which has an insulating board, conductor circuits, and through-holes, the insulating board having a top surface and a bottom surface, the conductor circuits being formed on the top surface and the bottom surface of the insulating board, the through-holes penetrating through the insulating board and electrically connecting the conductor circuit of the top surface and the conductor circuit of the bottom surface; and a plurality of conductor posts, each of which has a flange portion, a head portion, and a leg portion, the flange portion having a first surface and a second surface on an opposite side of the first surface and having an external diameter larger than a diameter of each of the through-holes, the head portion protruding from the first surface of the flange portion, the leg portion protruding from the second surface of the flange portion, wherein the leg portion of each of the conductor posts is connected to the electrode of a respective one of the electronic components, the head portion of each of the conductor posts is inserted into a respective one of the through-holes such that the first surface of the flange portion of each of the conductor posts comes into contact with the bottom surface of a respective one of the wiring boards and the head portion of each of the conductor posts is electrically connected at an inner wall of a respective one of the through-holes.
