Abstract

Semiconductor chips are provided. The semiconductor chip includes a semiconductor chip body having an arch-shaped groove in a backside thereof and a non-conductive material pattern filling the arch-shaped groove. Related methods are also provided.

Claims (18)

1. A semiconductor chip comprising:

a semiconductor chip body having an arch-shaped groove in a backside thereof; and

a non-conductive material pattern filling the arch-shaped groove,

wherein a surface of the non-conductive material pattern is coplanar with a bottom surface of the semiconductor chip body.

2. The semiconductor chip of claim 1 , wherein the non-conductive material pattern is a material having a solidity which is greater than that of the semiconductor chip body.

3. The semiconductor chip of claim 1 , wherein the non-conductive material pattern has an adhesive property.

4. The semiconductor chip of claim 1 , wherein the non-conductive material pattern includes an epoxy type polymer material or a silicon resin material.

5. The semiconductor chip of claim 1 , wherein the non-conductive material pattern comprises a material having substantially the same grinding rate as the semiconductor chip body.

6. A semiconductor package comprising:

a substrate;

a semiconductor chip attached to the substrate, the semiconductor chip including a semiconductor chip body having an arch-shaped groove in a backside thereof and a non-conductive material pattern filling the arch-shaped groove; and

a mold resin material encapsulating the semiconductor chip,

wherein a surface of the non-conductive material pattern is coplanar with a bottom surface of the semiconductor chip body.

7. The semiconductor package of claim 6 , wherein the semiconductor chip is electrically connected to the substrate through wires, the mold resin material encapsulating the semiconductor chip and wires.

8. The semiconductor package of claim 6 , wherein the non-conductive material pattern is a material having a solidity which is greater than that of the semiconductor chip body.

9. The semiconductor package of claim 6 , wherein the non-conductive material pattern has an adhesive property.

10. The semiconductor package of claim 6 , wherein the non-conductive material pattern includes an epoxy type polymer material or a silicon resin material.

11. The semiconductor package of claim 6 , wherein the non-conductive material pattern is attached to the substrate.
