Semiconductor device and method of designing the same

A semiconductor device comprising:

• an interposer having a rectangular planar geometry with length X for a first edge and length Y for a second edge orthogonal to said first edge;
• a semiconductor chip disposed over said interposer;
• and
• a dummy component disposed over said interposer, alongside of said semiconductor chip,
• wherein the center of a first outer circumferential region, which surrounds said semiconductor chip over said interposer, and has length “a” for a third edge lying in parallel with said first edge, and length “b” for a fourth edge orthogonal to said third edge, does not coincide with the center of said interposer, or equation X:Y=a:b is not satisfied, and
• the center of a second outer circumferential region, which surrounds said first outer circumferential region and said dummy component disposed over said interposer, and has length “x” for a fifth edge lying in parallel with said first edge, and length “y” for a sixth edge orthogonal to said fifth edge, coincides with the center of said interposer, and equation X:Y=x:y is satisfied.
