  • Patent number: 8115321
    Abstract: An integrated circuit includes a number of probe pads arranged in a staggered manner in a core region of the integrated circuit and a number of bond pads in an Input/Output (I/O) region surrounding the core region. The core region includes logic circuitry therein, and the I/O region is configured to enable the core region to communicate with one or more external circuit(s) through the number of bond pads. The integrated circuit also includes a die metal interconnect separating a bond pad area in the I/O region from a probe pad area in the core region. A dimension of the die metal interconnect and/or a position of the die metal interconnect between the probe pad area and the bond pad area is variable.

  • Publication number: 20100276816
    Abstract: Disclosed are a system and method of separate probe and bond regions of an integrated circuit (IC). An IC, an I/O region adjacent to the core region to enable the core region, and a die metal interconnect separating a bond pad area in the I/O region from a probe pad area outside the I/O region of the IC are disclosed. The die metal interconnect may have a length that is greater than the bond pad area length and/or the probe pad area length, and a width that is less than the bond pad area width and/or the probe pad area width. An in-front staggering technique may be used at a die corner of the IC to maintain the bond pad area in the I/O region, and a side staggering technique may be used at the die corner of the IC to maintain the bond pad area in the I/O region.
