Abstract:
Methods for forming an edge contact on a die and edge contact structures are described. The edge contacts on the die do not increase the height of the die. The edge contacts are positioned on the periphery of a die. The edge contacts are positioned in the saw streets. Each edge contact is connected to one bond pad of each die adjacent the saw street. The edge contact is divided into contacts for each adjacent die when the dies are separated. In an embodiment, a recess is formed in the saw street. In an embodiment, the recess is formed by scribing the saw street with a mechanical cutter. The recess is patterned and contact material is deposited to form the edge contacts.
