Abstract
A semiconductor device has a semiconductor substrate and first insulating layer formed over the surface of the semiconductor substrate. A dummy via is formed through the first insulating layer. A second insulating layer is formed over the first insulating layer to fill the dummy via. A first conductive layer is formed over the second insulating layer. A bump is formed over the first conductive layer adjacent to the dummy via filled with the second insulating layer. A second conductive layer is formed over a surface of the semiconductor substrate. The dummy via filled with the second insulating layer relieves stress on the second conductive layer. A plurality of dummy vias filled with the second insulating layer can be formed within a designated via formation area. A plurality of dummy vias filled with the second insulating layer can be formed in a pattern.
