Abstract:
1. A semiconductor device comprising: at least one semiconductor element; a first substrate being disposed to face one main surface of the semiconductor element, being provided a plurality of first internal wirings on a main surface of the first substrate on a side facing the semiconductor element, and being provided a plurality of first external wirings being electrically connected to the respective first internal wirings on a main surface of the first substrate on a side opposite to the side facing the semiconductor element; and a second substrate being formed to be larger than both main surfaces of the semiconductor element by a material having flexibility, being disposed to hold the semiconductor element between the first substrate and the second substrate, being provided a plurality of second internal wirings having one-end portions extended to edges of a main surface of the second substrate on a side facing the semiconductor element on the main surface of the second substrate on the side facing the semiconductor element, and the one-end portions of the second internal wirings electrically connected to the first internal wirings with being bent toward the first substrate together with the edges of the second substrate on which the second internal wirings are provided, being mounted the semiconductor element having at least one electrode electrically connected to some of the second internal wirings on the main surface of the second substrate on the side facing the semiconductor element, and being provided a plurality of external terminals being electrically connected to some of the second internal wirings on at least a middle part of a main surface of the second substrate on a side opposite to the side on which the semiconductor element is mounted.
