Semiconductor device and method of designing the same
View Patent ↗A semiconductor device contains an interposer having a square planar geometry, with length X for a first edge and length Y for a second edge orthogonal to the first edge, and a semiconductor chip and a dummy component disposed over the interposer, wherein the center of a first outer circumferential region, which surrounds the semiconductor chip over the interposer, and has length “a” for a third edge, and length “b” for a fourth edge, does not coincide with the center of the interposer, or equation X:Y=a:b is not satisfied, and the center of a second outer circumferential region, which surrounds the first outer circumferential region and the dummy components disposed over the interposer, and has length “x” for a fifth edge, and length “y” for a sixth edge, coincides with the center of the interposer, and equation X:Y=x:y is satisfied.
1. 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.
2. The semiconductor device as claimed in claim 1 ,
wherein said dummy component are disposed so as to make an area, having said dummy component and said semiconductor chip disposed therein, symmetrical about both of a first center line of said interposer and a second center line orthogonal to said first center line, in a plan view.
3. The semiconductor device as claimed in claim 1 ,
having a plurality of said semiconductor chips disposed over said interposer, and
said first outer circumferential region surrounds said plurality of semiconductor chips.
4. The semiconductor device as claimed in claim 1 ,
wherein said dummy component is any one of passive component, dummy semiconductor chip, or component composed of a silicon, ceramic or metal material.
5. The semiconductor device as claimed in claim 1 ,
further comprising a radiator plate provided over said interposer, and provided over at least either one of said semiconductor chip and said dummy component, while being bonded to at least either one of them.
6. The semiconductor device as claimed in claim 1 ,
further comprising a radiator plate provided over said interposer, configured by the same material with said dummy component, and formed while being integrated with said dummy component.
