  • Patent number: 8922001
    Abstract: A semiconductor device in which warpage is less likely to occur. In the semiconductor device, two semiconductor chips are mounted over a diagonal of a substrate and one of the semiconductor chips lies over the intersection of the two diagonals of the substrate. The semiconductor device gives a solution to the following problem. In order to implement a semiconductor device with a plurality of semiconductor chips mounted on a substrate, generally the substrate must have a larger area. If the area of the substrate is increased without an increase in its thickness, warpage or deformation of the semiconductor device is more likely to occur. It is difficult or impossible to mount a warped or deformed semiconductor device over a wiring substrate.
