Patent ID: 7626263

Claim:
A semiconductor device, comprising: a first bump column on an active surface of the semiconductor device, the first bump column including a plurality of first bumps spaced a first distance from an edge of the semiconductor device; a second bump column on the active surface, the second bump column including a plurality of second bumps spaced a second distance from the edge of the semiconductor device, wherein the second distance is greater than the first distance; and a third bump column on the active surface, the third bump column including a plurality of third bumps spaced a third distance from the edge of the semiconductor device, wherein the third distance is greater than the second distance, wherein the second bumps and the third bumps are sequentially alternated one by one at least twice between the first bumps, and wherein bumps directly adjacent to each other in a parallel direction with the edge of the semiconductor device are on different ones of the first bump column, the second bump column, and the third bump column.
