Abstract
A semiconductor device includes a package substrate, a semiconductor chip on a first region of the package substrate, and a solder bump on a second region of the package substrate. The solder bump includes a core portion and a peripheral portion encapsulating the core portion. The peripheral portion includes a first segment with a first melting point and a second segment with a second melting point that is less than the first melting point.
