22b are alternately arranged from the edge toward the center of an active surface of the semiconductor device 20. The first and second bump columns 22a and 22b may be arranged in a staggered formation.
Leads 12a and 12b of the wiring substrate 10 may correspond to the first and second bump columns 22a and 22b of the semiconductor device 20. The leads 12a and 12b may include first bump column leads 12a and second bump column leads 12b that respectively correspond to the first bump column 22a and the second bump column 22b. 
To align the first and second bump columns 22a and 22b correspondingly with the first and second bump column leads 12a and 12b, the semiconductor device 20 is disposed in a mounting region of thePresident Obama was speaking at a campaign even in Cleveland, Ohio today, which was enough for the Romney campaign, which also happened to be in town, to pull a bit of a campaign prank: drive around the event in circles, honking the horn to drown out the Democrats.
