Abstract
An integrated circuit topography is provided which includes at least two rows of bonding pads. Each row of bonding pads is attributed a row of probe pads. One row of probe pads is contained within the scribe area and suffices as a sacrificial row of probe pads. The other row of probe pads is placed toward the interior of the integrated circuit. The rows of bonding pads and probe pads extend along parallel axis around all four sides of the integrated circuit. Every other bonding pad within one row of bonding pads is connected to every other probe pad within the scribe area, and every other bonding pad within the other rows of bonding pads is connected to every probe pad within the row of probe pads interior to the integrated circuit. This allows a fan-out configuration of the bonding pads to probe pads for purposes of probing electrical performance of the integrated circuit without having to use selected ones of the bonding pads. This prevents jeopardizing the integrity of the bonding pad by gouging out the bonding pad during probe operation. Moreover, thicker probe needles can be used, and placed in a less dense fashion around the outer perimeter of the integrated circuit.
