| Claim: | 1. An integrated circuit, comprising: a first seal ring, disposed in the integrated circuit, the first seal ring comprising at least one staggered structure, wherein the at least one staggered structure comprises at least one staggered unit, and the at least one staggered unit makes a staggered connection with another neighboring stagger unit, wherein a width of a connection plane between the at least one staggered structure and another staggered unit neighboring to the at least one staggered structure is less than a width of the first seal ring, and wherein the at least one staggered unit and the another staggered unit neighboring to the at least one staggered unit are connected to each other by no more than one point and are connected to each other in a staggered manner. |
| Claim: | 2. The integrated circuit of claim 1 , wherein the connection planes of different staggered units have different widths. |
| Claim: | 3. The integrated circuit of claim 1 , wherein the at least one staggered unit have one of the following groups: different volumes; and different shapes. |
| Claim: | 4. The integrated circuit of claim 1 , wherein the first seal ring comprising at least one continuous segment structure, and the at least one staggered unit makes a staggered connection with the at least one continuous segment structure. |
| Claim: | 5. The integrated circuit of claim 1 , further comprising: a second seal ring, disposed in the integrated circuit and surrounding the first seal ring. |
| Claim: | 6. The integrated circuit of claim 5 , wherein the second seal ring encloses a closed area. |
| Claim: | 7. The integrated circuit of claim 5 , wherein the second seal ring is of a continuous segment structure. |
| Claim: | 8. The integrated circuit of claim 5 , wherein the second seal ring have different widths. |
| Claim: | 9. A seal ring in an integrated circuit, the seal ring being disposed in the integrated circuit, the seal ring comprising: at least one staggered structure, wherein the at least one staggered structure comprises at least one staggered unit, the at least one staggered unit makes a staggered connection with another neighboring stagger unit, wherein a width of a connection plane between the at least one staggered structure and another staggered unit neighboring to the at least one staggered structure is less than a width of the first seal ring, and wherein the at least one staggered unit and the another staggered unit neighboring to the at least one staggered unit are connected to each other by no more than one point and are connected to each other in a staggered manner. |
| Claim: | 10. The seal ring in an integrated circuit of claim 9 wherein the connection planes of different staggered units have different widths. |
| Claim: | 11. The seal ring in an integrated circuit of claim 9 , wherein the at least one staggered unit have one of the following groups: different volumes; and different shapes. |
| Claim: | 12. The seal ring in an integrated circuit of claim 9 , wherein the first seal ring comprising at least one continuous segment structure. |
| Claim: | 13. The seal ring in an integrated circuit of claim 12 , wherein the at least one staggered unit makes a staggered connection with the at least one continuous segment structure. |
| Claim: | 14. The seal ring in an integrated circuit of claim 13 , wherein a width of a connection plane between the at least one staggered structure and the at least one continuous segment structure is less than a pre-determined width value. |
