| abstract |
A semiconductor device including a substrate having a first surface and a second surface facing the first surface, the substrate having a via hole, the via hole extending from the first surface of the substrate toward the second surface of the substrate, a through via in the via hole, a semiconductor component on the first surface of the substrate, and an internal buffer structure spaced apart from the via hole and between the via hole and the semiconductor component, the internal buffer structure extending from the first surface of the substrate toward an inside of the substrate, a top end of the internal buffer structure being at a level higher than a top end of the through via may be provided. |
