Patent ID: 7531898

Claim:
An integrated circuit device comprising: a substrate; a conductive pad on a surface of the substrate; a conductive line on the surface of the substrate wherein the conductive line is connected to the conductive pad and wherein the conductive line is narrow relative to the conductive pad in a direction parallel with respect to the surface of the substrate; and an insulating layer on the substrate, on the conductive line, and on edge portions of the conductive pad wherein the insulating layer has a hole therein exposing a central portion of the conductive pad, and wherein a first segment of a perimeter of the hole substantially defines an arc of a circle around the central portion of the conductive pad and wherein a second segment of the perimeter of the hole substantially deviates from the circle around the central portion of the conductive pad, and wherein the second segment of the perimeter of the hole is adjacent a connection between the conductive line and the conductive pad.
