Patent ID: 7701056

Claim:
A redistribution connecting structure for solder balls, comprising: a substrate; a first bonding pad and a second bonding pad disposed on the substrate; a first dielectric layer disposed on the substrate, wherein the first dielectric layer comprises a first opening and a second opening for exposing a portion of the first bonding pad and the second bonding pad respectively; a redistribution conductive layer having a first redistribution pad and a second redistribution pad disposed on the first dielectric layer, wherein the first redistribution pad is disposed adjacent to the second bonding pad and electrically connected to the first bonding pad through the first opening, and the second redistribution pad is electrically connected to the second bonding pad through the second opening; a second dielectric layer having a third opening and a fourth opening disposed on the first dielectric layer and the redistribution conductive layer, wherein the third opening exposes a portion of the first redistribution pad and the fourth opening exposes a portion of the second redistribution pad; and a first solder ball disposed on the first redistribution pad, wherein the surface of the first solder ball covers the third opening and a portion of the second opening, and the third opening is substantially circular and comprises a cut-off portion, such that the third opening is adjacent but not overlapping the second opening.
