Abstract

The embodiments of the present invention discloses an arrangement of bond pads on an integrated circuit chip. The integrated circuit chip includes: a first row of bond pads; and a second row of bond pads, wherein bond pads in the first row are positioned alternately with bond pads in the second row, and a short side of the bond pads in the first row and the second row is parallel to a long side of the integrated circuit chip. With this arrangement of bond pads on the integrated circuit chip, the bond pads may occupy a reduced area of a surface of the integrated circuit chip.

Claims (21)

1. An integrated circuit chip, comprising:

a first row of bond pads, wherein the first row of bond pads include a first group of bond pads and a second group of bond pads; and

a second row of bond pads, wherein the second row of bond pads include a third group of bond pads and a fourth group of bond pads, wherein the first group of bond pads and the second group of bond pads in the first row are positioned alternately with the third group of bond pads and the fourth group of bond pads in the second row, and a short side of the bond pads in the first row and the second row is parallel to a long side of the integrated circuit chip,

and wherein each of the first group, the second group, the third group, and the fourth group includes more than one bond pads.

2. The integrated circuit chip of claim 1 , wherein

the integrated circuit chip comprises a first side and a second side that are parallel to a first direction and a third side and a fourth side that are parallel to a second direction, and lengths of the first side and the second side of the integrated circuit chip are greater than lengths of the third side and the fourth side of the integrated circuit chip; and

each bond pad in the first row and the second row comprises a first side and a second side that are parallel to the second direction and a third side and a fourth side that are parallel to the first direction, and lengths of the first side and the second side of each bond pad are greater than lengths of the third side and the fourth side of each bond pad.

3. The integrated circuit chip of claim 2 , wherein the fourth side of the bond pads of the first row is spaced from the third side of the bond pads of the second row by a distance greater than or equal to a first threshold in the second direction.

4. The integrated circuit chip of claim 2 , wherein neighboring pads in the first row of pads are spaced from each other by a distance greater than or equal to a second threshold in the first direction, and neighboring pads in the second row of pads are spaced from each other by a distance greater than or equal to the second threshold in the first direction.

5. The integrated circuit chip of claim 1 , further comprising:

a third row of bond pads adjacent to the second row, wherein bond pads of the third row are positioned alternately with the bond pads of the second row.

6. The integrated circuit chip of claim 1 , wherein at least one of the bond pads has at least one rounded corner.

7. The integrated circuit chip of claim 6 , wherein the at least one rounded corner is located on a side of a bond pad of the first row adjacent to the second row, or located on a side of a bond pad of the second row adjacent to the first row.

8. The integrated circuit chip of claim 6 , wherein the at least one rounded corner has a central angle greater than or equal to 30 degrees and less than 90 degrees.

9. The integrated circuit chip of claim 1 , wherein at least one of the bond pads has at least one chamfered corner.

10. The integrated circuit chip of claim 9 , wherein the at least one chamfered corner is located on a side of a bond pad of the first row adjacent to the second row, or located on a side of a bond pad of the second row adjacent to the first row.

11. The integrated circuit chip of claim 9 , wherein the at least one chamfered corner has a chamfer angle greater than or equal to 30 degrees and less than 90 degrees.

12. The integrated circuit chip of claim 1 , wherein at least one corner of at least one of the bond pads includes one of a concave corner, a convex corner, or a chamfered corner.

13. The integrated circuit chip of claim 1 , wherein a number of bond pads in the first row is the same as or different than a number of bond pads in the second row.

14. The integrated circuit chip of claim 1 , wherein the first group of bond pads comprises a first number of bond pads, the second group of bond pads comprises a second number of bond pads, and the first number is the same as or different than the second number.

15. The integrated circuit chip of claim 1 , wherein the third group of bond pads comprises a third number of bond pads, the fourth group of bond pads comprises a fourth number of bond pads, and the third number is the same as or different than the fourth number.
