Patent ID: 7932615

Claim:
An electronic device comprising: a substrate including a first input/output pad and a second input/output pad thereon; a compliant dielectric layer on a first portion of the substrate wherein a second portion of the substrate is free of the compliant dielectric layer; a first conductive redistribution line extending from the first input/output pad to the compliant dielectric layer so that the compliant dielectric layer is between a bump pad portion of the first conductive redistribution line and the substrate; a first solder bump on the bump pad portion of the first conductive redistribution line so that the compliant dielectric layer is between the first solder bump and the substrate; a second solder bump on the second portion of the substrate that is free of the compliant dielectric layer; and a second conductive redistribution line extending from the second input/output pad to the second solder bump so that a bump pad portion of the second conductive redistribution line is between the second solder bump and the second portion of the substrate; wherein the second conductive redistribution line comprises a narrow portion between the bump pad portion and the second input/output pad wherein the narrow portion of the second redistribution line extends across the compliant dielectric layer.
