Abstract:
1. A semiconductor device comprising: a support substrate; a first semiconductor element that is mounted on one side of the support substrate; a second semiconductor element including a high frequency electrode that is mounted on said one side of the support substrate; a via hole that is provided at the support substrate in relation to the high frequency electrode; an external connection electrode that is provided on the other side of the support substrate in relation to the via hole; wherein a center axis of the high frequency electrode is positioned within a periphery of the via hole; the via hole related to the high frequency electrode has a diameter larger than a diameter of a second via hole connected to a second electrode of said second semiconductor element; and the diameter of the via hole related to the high frequency electrode is larger than a diameter of the external connection electrode of said second semiconductor element connecting to said via hole related to the high frequency electrode.
