Post passivation interconnection schemes on top of the IC chips
摘要:
A new method is provided for the creation of interconnect lines. Fine line interconnects are provided in a first layer of dielectric overlying semiconductor circuits that have been created in or on the surface of a substrate. A layer of passivation is deposited over the layer of dielectric and a thick second layer of dielectric is created over the surface of the layer of passivation. Thick and wide post-passivation interconnect lines are created in the thick second layer of dielectric. The first layer of dielectric may also be eliminated, creating the wide thick passivation interconnect network on the surface of the layer of passivation that has been deposited over the surface of a substrate.
