Abstract

Substrates and semiconductor chips are provided. The substrate or the semiconductor chip includes a body and a substantially pillar-shaped bump disposed on a first surface of the body. The pillar-shaped bump has a hole penetrating a portion thereof. Related semiconductor packages are also provided. Further, related methods are provided.

Claims (27)

1. A substrate comprising:

a substrate body; and

a substantially pillar-shaped bump disposed on a first surface of the substrate body,

wherein a hole extends through the pillar-shaped bump and is substantially parallel to the first surface, and

wherein the area of the cross-section of the hole is smaller than the remaining area of the cross-section of the pillar-shaped bump.

2. The substrate of claim 1 , wherein the substantially pillar-shaped bump includes a conductive material.

3. The substrate of claim 1 , wherein the hole extends through and is surrounded by the substantially pillar-shaped bump.

4. A semiconductor chip comprising:

a chip body; and

a substantially pillar-shaped bump disposed on a first surface of the chip body,

wherein a hole extends through the substantially pillar-shaped bump,

wherein the hole is substantially parallel to the first surface, and

wherein the area of the cross-section of the hole is smaller than the remaining area of the cross-section of the pillar-shaped bump.

5. The semiconductor chip of claim 4 , wherein the substantially pillar-shaped bump includes a conductive material.

6. The semiconductor chip of claim 4 , wherein the hole extends through and is surrounded by the substantially pillar-shaped bump.

7. A semiconductor package comprising:

a substrate having a substrate body and a substantially pillar-shaped bump disposed on a first surface of the substrate body, wherein a hole extends through two sides of the substantially pillar-shaped bump hole and is substantially parallel to the first surface, wherein the area of the cross-section of the hole is smaller than the remaining area of the cross-section of the pillar-shaped bump;

a semiconductor chip having a chip body and a conductive electrode pattern disposed on a first surface of the chip body; and

an adhesive agent substantially filling the hole and bonding the conductive electrode pattern to the substantially pillar-shaped bump.

8. The semiconductor package of claim 7 , wherein the conductive electrode pattern includes a bump.

9. The semiconductor package of claim 7 , wherein the adhesive agent includes a solder material.

10. A semiconductor package comprising:

a semiconductor chip having a chip body and a substantially pillar-shaped bump disposed on a first surface of the chip body, wherein a hole extends through the substantially pillar-shaped bump, wherein the hole is substantially parallel to the first surface, wherein the area of the cross-section of the hole is smaller than the remaining area of the cross-section of the pillar-shaped bump;

a substrate having a substrate body and a conductive electrode pattern disposed on a first surface of the substrate body; and

an adhesive agent substantially filling the hole and electrically coupling the conductive electrode pattern to the substantially pillar-shaped bump.

11. The semiconductor package of claim 10 , wherein the conductive electrode pattern includes a bump.

12. The semiconductor package of claim 10 , wherein the adhesive agent includes a solder material.
