The present invention relates to a chip having a bump and a package having the same. The chip includes a chip body, at least one via, a passivation layer, an under ball metal layer and at least one bump. The via penetrates the chip body, and is exposed to a surface of the chip body. The passivation layer is disposed on the surface of the chip body, and the passivation layer has at least one opening. The opening exposes the via. The under ball metal layer is disposed in the opening of the passivation layer, and is connected to the via. The bump is disposed on the under ball metal layer, and includes a first metal layer, a second metal layer and a third metal layer. The first metal layer is disposed on the under ball metal layer. The second metal layer is disposed on the first metal layer. The third metal layer is disposed on the second metal layer. As the bumps can connect two chips, the chip is stackable, and so the density of the product is increased while the size of the product is reduced.
