1. An apparatus comprising:

  • a first conductive layer to provide conductive interconnects for pad diffusion regions and supply diffusion regions in a diode; and

    a second conductive layer coupled with the first conductive layer, the second conductive layer including a first portion to couple the pad diffusion regions with a pad and a second portion to couple the supply diffusion regions with a voltage supply,wherein the first and the second conductive layers having conductive lines being parallel to each other in a diode region of the diode,wherein the first portion of the second conductive layer extends less than half way across the diode region from a first side of the diode region, andwherein the second portion of the second conductive layer extends less than half way across the diode region from an opposite side of the diode region.
