The connection technology is provided in which, at the time of mounting the semiconductor device on the substrate, the thermal load or the stress, which is imposed upon the semiconductor device, is little, a reliability of the semiconductor device is obtained, a stand-off of the semiconductor device mounted on the substrate can be secured appropriately, and moreover the short circuit hardly occurs between the pads of the semiconductor device mounted on the substrate.
The semiconductor device mounted on the substrate, in which the substrate includes an electrode pad, the semiconductor device includes an electrode pad, the electrode pad of the semiconductor device and the electrode pad of the substrate are connected with a conductive adhesive, and a spacer is provided between the semiconductor device and the substrate.
