A semiconductor chip includes a first substrate including a first surface and a second surface, a through-via plug passing through the first substrate, and a first conduction layer connected to an end of the through-via plug on the first surface, and a first bump including a first barrier layer on the first conduction layer, and a first solder layer for connecting the first substrate and a second substrate on the first barrier layer, and the first barrier layer includes a barrier material for preventing diffusion of a conductive material of the first conduction layer into the first solder layer. |
