  • Publication number: 20230096170
    Abstract: A semiconductor package may include vertically-stacked semiconductor chips and first, second, and third connection terminals connecting the semiconductor chips to each other. Each of the semiconductor chips may include a semiconductor substrate, an interconnection layer on the semiconductor substrate, penetration electrodes connected to the interconnection layer through the semiconductor substrate, and first, second, and third groups on the interconnection layer. The interconnection layer may include an insulating layer and first and second metal layers in the insulating layer. The first and second groups may be in contact with the second metal layer, and the third group may be spaced apart from the second metal layer. Each of the first and third groups may include pads connected to a corresponding one of the first and third connection terminals in a many-to-one manner. The second group may include pads connected to the second connection terminal in a one-to-one manner.
