An object of the present technology is to prevent damage in a bonded portion between a semiconductor chip and a substrate in a semiconductor device in which the semiconductor chip is mounted on the substrate. A terminal is disposed between an electrode of an element and an electrode of a substrate on which the element is mounted, and electrically connects the electrode of the element and the electrode of the substrate. The terminal includes a plurality of unit lattices and a coupling portion. The unit lattices included in the terminal are formed by bonding a plurality of beams in a cube shape. The coupling portion included in the terminal couples adjacent unit lattices among the plurality of unit lattices.

A method for attaching an integrated circuit (IC) to an IC package substrate includes forming a solder bump on a bond pad of an IC die, forming a solder-wetting protrusion on a bond pad of an IC package substrate, and bonding the solder bump of the IC die to the solder-wetting protrusion of the IC package substrate.
