Abstract:
1. A semiconductor device comprising: a semiconductor die comprising a slant surface slanting from a back surface of the semiconductor die and connecting the back surface and an outside side surface of the semiconductor die; a pad electrode formed on a front surface of the semiconductor die; an embedded electrode that is disposed in a via hole formed in the semiconductor die and is in contact with the pad electrode; a wiring layer that is in contact with the embedded electrode and covers the slant surface; a circuit board on which the semiconductor die is mounted so that the back surface of the semiconductor die faces the circuit board; and a conductive fillet connecting the slant surface of the semiconductor die and the circuit board, wherein the pad electrode covers the via hole formed in the semiconductor die, and the conductive fillet extends away from the embedded electrode and beyond a contour of the semiconductor die defined by the outside side surface.
