A semiconductor device includes a main surface, a back surface opposite to the main surface, a first side on the main surface, a second side opposite to the first side, a third side between the first side and the second side, a fourth side opposite to the third side, a first point on a periphery of the main surface between the first side and the third side, a second point on the periphery of the main surface between the second side and the fourth side, a third point on the periphery of the main surface between the first side and the fourth side, and a fourth point on the periphery of the main surface between the third side and the second side, a first semiconductor chip disposed over the main surface of the substrate, and a second semiconductor chip disposed over the main surface of the substrate.

Semiconductor device

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.
