Abstract:
1. A semiconductor device comprising: a first base material which is provided at least one semiconductor device mounted on one main surface of the first base material, a plurality of first connection portions provided on the main surface of the first base material on the side on which the semiconductor device is mounted and being electrically connected to the semiconductor device, and a plurality of second connection portions provided outside a region on which the semiconductor device is mounted on the main surface of the first base material on the side on which the semiconductor device is mounted; and a second base material which is disposed facing the main surface of the first base material on a side opposite to the side on which the semiconductor device is mounted, bonded to an edge of the first base material so that the first base material is mounted on the second base material, and provided a plurality of third connection portions provided outside a region on which the first base material is mounted on the main surface of the second base material on the side facing the first base material and being electrically connected to at least one of the second connection portions.
