A chip stack package includes a first semiconductor chip, a second semiconductor chip and a third semiconductor chip. The first semiconductor chip includes a first through silicon via that extends through the first semiconductor chip. The second semiconductor chip is stacked on the first semiconductor chip, and includes a second through silicon via that extends through the second semiconductor chip. The second through silicon via is disposed on the first through silicon via, and has a cross-sectional area smaller than that of the first through silicon via. The third semiconductor chip is stacked on the first semiconductor chip, and includes a third through silicon via that extends through the third semiconductor chip. The third through silicon via is disposed on the second through silicon via, and has a cross-sectional area smaller than that of the second through silicon via. |
