A multi-chip package may include a package substrate, an interposer chip, a first semiconductor chip, a thermal dissipation structure and a second semiconductor chip. The interposer chip may be mounted on the package substrate. The first semiconductor chip may be mounted on the interposer chip. The first semiconductor chip may have a size smaller than that of the interposer chip. The thermal dissipation structure may be arranged on the interposer chip to surround the first semiconductor chip. The thermal dissipation structure may transfer heat in the first semiconductor chip to the interposer chip. The second semiconductor chip may be mounted on the first semiconductor chip. Thus, the heat in the first semiconductor chip may be effectively transferred to the interposer chip through the thermal dissipation line.
