Claim:
1. A semiconductor device having improved heat-dissipation characteristics, comprising: a first semiconductor chip having a plurality of dummy connectors and a plurality of internal connectors for an electrical coupling of an internal circuit formed in a first semiconductor substrate; and a second semiconductor chip having a plurality of dummy connectors and a plurality of internal connectors for an electrical coupling of an internal circuit formed in a second semiconductor substrate, and stacked on an upper portion of the first semiconductor chip, wherein at least one of the plurality of dummy connectors of the first semiconductor chip is coupled through a routing of a dummy metal distribution line of the first semiconductor chip, and at least one of the plurality of dummy connectors of the second semiconductor chip is coupled through a routing of a dummy metal distribution line of the second semiconductor chip, wherein a heat generated from a hot spot of the semiconductor device is dissipated to an entire portion of the semiconductor device through the dummy metal distribution line and the dummy connector, and wherein a through-silicon via (TSV) for discharging a heat, which is dissipated to the semiconductor device, to outside the semiconductor device is further disposed in at least one of the first semiconductor chip and the second semiconductor chip, and wherein the TSV is coupled to the dummy metal distribution line coupled to the dummy connector.
