Patent ID: 7498260

Claim:
A method for forming a semiconductor device, comprising: forming a first opening through a first conductive pad and a second opening through a second conductive pad, wherein the first and second openings have about the same width; forming a dielectric material over the first and second conductive pads and within the first and second openings; forming a mask comprising: a first opening having a width about the same as the opening in the first conductive pad and which overlies the opening in the first conductive pad; and a second opening having a width which is larger than the opening in the second conductive pad and which overlies the opening in the second conductive pad; etching a semiconductor wafer through the first and second openings in the mask and through the openings in the first and second conductive pads to form first and second openings in the semiconductor wafer; and forming a conductive material within the first and second openings in the semiconductor wafer, within the first opening though the first conductive pad, and within the second opening through the second conductive pad such that the conductive material is electrically coupled with the second conductive pad and is electrically isolated from the first conductive pad.
