Abstract:
1. A semiconductor device having a functional surface that provides a predetermined function, the semiconductor device comprising: a semiconductor element having a circuit formation surface on which a plurality of electrodes are formed and a back surface opposite to the circuit formation surface, a part of the circuit formation surface functioning as said functional surface; a first resin provided on the circuit formation surface of said semiconductor element and exposing said functional surface from the semiconductor device; wiring formed on said back surface of the semiconductor element; a plurality of connection parts extending between said circuit formation surface and said back surface of said semiconductor element so as to electrically connect the electrodes to said wiring; a second resin formed on said back surface of said semiconductor element so as to cover said wiring; and a plurality of external connection terminals protruding from a surface of said second resin on a side of said back surface of said semiconductor element, wherein a side surface of said semiconductor element includes a first slanting surface that is slanted with respect to said circuit formation surface, the first slanting surface covered by said first resin and the side surface of said semiconductor element includes a second slanting surface that is slanted with respect to said back surface, the second slanting surface covered by said second resin, and the side surface of said semiconductor element includes an uncovered middle surface between the first and second slanting surfaces.
