A multi-chip package may include a first semiconductor package, a second semiconductor package and an interposer chip. The second semiconductor package may be arranged over the first semiconductor package. The interposer chip may be interposed between the first semiconductor package and the second semiconductor package. The interposer chip may have a receiving groove configured to receive the first semiconductor package. Thus, electrical connection reliability between the first semiconductor package and the second semiconductor package may be improved under a condition that the connecting terminals may have small sizes.

In a semiconductor device stack package and a method of forming the same, the package comprises: a substrate; a plurality of lower chips stacked on the substrate and having an active surface oriented in a direction toward the substrate; and at least one upper chip disposed on the lower chips and connected to the substrate via a bump disposed between the lower chips. As no wire loops are formed, there is no increase in the height of the stack package, and the electrical path is shortened, thereby improving the electric performance of the stack package. Also, the semiconductor device stack package has a flip chip structure, and thus a plurality of semiconductor chips can be stacked in various manners.
