Abstract
A semiconductor package with solder bumps and a method for making the same are described. One embodiment comprises a flip-chip design with a rectangular semiconductor die with a relatively large aspect ratio bonded to a substantially square substrate through solder bumps. In one embodiment, active bumps are concentrated in an area relatively close to the neutral point of the die, for example, in a substantially square area about the neutral point.
