Patent ID: 8922001

Claim:
A semiconductor device comprising: a rectangular substrate having: a main surface; a back surface opposite thereto; a first side on the main surface; a second side opposite to the first side; a third side intersecting the first side and the second side; a fourth side opposite to the third side; a first corner where the first side and the third side intersect each other; a second corner where the second side and the fourth side intersect each other; a third corner where the first side and the fourth side intersect each other; and a fourth corner where the third side and the second side intersect each other; a first semiconductor chip lying over a virtual first diagonal coupling the first corner with the second corner over the main surface; and a second semiconductor chip lying over the first diagonal over the main surface, wherein the first semiconductor chip lies over an intersection between a virtual second diagonal coupling the third corner with the fourth corner over the main surface and the first diagonal.
