The present invention provides a system and method for preventing cracking in a passivation protective layer. In one embodiment, a contact pad has a first diameter, and one opening through the passivation protective layer has a second diameter, wherein the first diameter is greater than the second diameter by a first distance, which is about 10 microns. In another embodiment, a bump underlayer metal layer passes through the opening and has a third diameter, wherein the third diameter is greater than the first diameter by a second distance, which is 5 microns. In yet another embodiment, the sum of the first distance and the second distance is greater than 15 microns. |
