Abstract
Provided are embodiments of semiconductor chips having a redistributed metal interconnection directly connected to power/ground lines of an internal circuit are provided. Embodiments of the semiconductor chips include an internal circuit formed on a semiconductor substrate. A chip pad is disposed on the semiconductor substrate. The chip pad is electrically connected to the internal circuit through an internal interconnection. A passivation layer is provided over the chip pad. A redistributed metal interconnection is provided on the passivation layer. The redistributed metal interconnection directly connects the internal interconnection to the chip pad through a via-hole and a chip pad opening, which penetrate at least the passivation layer. Methods of fabricating the semiconductor chip are also provided.
