Claim Text:
1. A semiconductor device, comprising: a substrate including a first lead finger and second lead finger adjacent to the first lead finger, the first lead finger and second lead finger comprising a surface disposed at a same level around a die area; a semiconductor die disposed over the substrate; a first conductive layer formed over the surface of the first lead finger; a second conductive layer formed over the surface of the second lead finger, wherein a thickness of the second conductive layer is greater than a thickness of the first conductive layer; a first bump formed over the first conductive layer at a first distance from the semiconductor die with a width of the first bump greater than a width of the first conductive layer; and a second bump formed over the second conductive layer at a second distance from the semiconductor die with the second distance substantially equal to the first distance, the first bump overlaps the second bump and the first bump and the second bump are physically separated due to the thickness of the second conductive layer being greater than the thickness of the first conductive layer.
