    摘要: A chip structure comprises a substrate, a first built-up layer, a passivation layer and a second built-up layer. The substrate includes many electric devices placed on a surface of the substrate. The first built-up layer is located on the substrate. The first built-up layer is provided with a first dielectric body and a first interconnection scheme, wherein the first interconnection scheme interlaces inside the first dielectric body and is electrically connected to the electric devices. The first interconnection scheme is constructed from first metal layers and plugs, wherein the neighboring first metal layers are electrically connected through the plugs. The passivation layer is disposed on the first built-up layer and is provided with openings exposing the first interconnection scheme. The second built-up layer is formed on the passivation layer. The second built-up layer is provided with a second dielectric body and a second interconnection scheme, wherein the second interconnection scheme interlaces inside the second dielectric body and is electrically connected to the first interconnection scheme. The second interconnection scheme is constructed from at least one second metal layer and at least one via metal filler, wherein the second metal layer is electrically connected to the via metal filler. The thickness, width, and cross-sectional area of the traces of the second metal layer are respectively larger than those of the first metal layers.

    摘要: A new post-passivation metal interconnect scheme is provided over the surface of a IC device that has been covered with a conventional layer of passivation. The metal scheme of the invention comprises, overlying a conventional layer of passivation, thick and wide metal lines in combination with thick layers of dielectric and bond pads. The interconnect system of the invention can be used for the distribution of power, ground, signal and clock lines from bond pads to circuits of a device that are provided in any location of the IC device without introducing significant power drop. No, or smaller ESD circuits are required due to the low impedance post-passivation interconnection, since any accumulated electrostatic discharge will be evenly distributed across all junction capacitance of the circuits on the chip. The post passivation metal scheme is connected to external circuits through bond pads, solder bonding, TAB bonding and the like. A top layer of the interconnect metal scheme is formed using a composite metal for purposes of wirebonding, the composite metal is created over a bulk conduction metal. A diffusion metal may be applied between the bulk metal and the composite metal, in addition a layer of Under-Barrier-Metal (UBM) may be required underneath the bulk conduction metal.
