Abstract

In one embodiment, a semiconductor chip has one or more peripheral bond pads. The semiconductor chip comprises a semiconductor substrate having a cell region and a peripheral circuit region adjacent to each other; a bond pad-wiring pattern formed on at least a part of the peripheral region of the semiconductor substrate; a passivation layer formed on the bond pad-wiring pattern and exposed portions of the semiconductor substrate; a pad-rearrangement pattern disposed over the passivation layer and electrically connected to the bond pad-wiring pattern; and an insulating layer formed over the pad-rearrangement pattern. The insulating layer has an opening therein that exposes a portion of the pad-rearrangement pattern to define a bond pad. The bond pad is disposed over at least a part of the cell region.
