    • A new method and structure is provided for the creation of a semiconductor inductor. Under the first embodiment of the invention, a semiconductor substrate is provided with a scribe line in a passive surface region and active circuits surrounding the passive region. At least one bond pad is created on the passive surface of the substrate close to and on each side of the scribe line. A layer of insulation is deposited, a layer of dielectric is deposited over the layer of insulation, at least one bond pad is provided on the surface of the layer of dielectric on each side of the scribe line. At least one inductor is created on each side of the scribe line on the surface of the layer of dielectric. A layer of passivation is deposited over the layer of dielectric. The substrate is attached to a glass panel by interfacing the surface of the layer of passivation with the glass panel. The substrate is sawed from the backside of the substrate in alignment with the scribe line. The silicon that remains in place in the passive surface of the substrate underneath the scribe lines is removed by etching, the glass panel is separated along the scribe line. Under the second embodiment of the invention, the inductor is created on the surface of a thick layer of polymer that is deposited over the layer of passivation.

    • 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.
    • 在已经被常规钝化层覆盖的IC器件的表面上提供了新的后钝化金属互连方案。 本发明的金属方案包括叠加常规的钝化层,厚和宽的金属线与厚的介电层和接合焊盘的组合。 本发明的互连系统可以用于将功率,接地,信号和时钟线从接合焊盘分配到设置在IC器件的任何位置的器件的电路,而不引入显着的功率下降。 由于低阻抗钝化后互连,不需要或更小的ESD电路,因为任何累积的静电放电将均匀分布在芯片上电路的所有结电容上。 后钝化金属方案通过接合焊盘,焊接,TAB接合等连接到外部电路。 互连金属方案的顶层使用用于引线键合的复合金属形成,复合金属在体导电金属上形成。 扩散金属可以施加在本体金属和复合金属之间,另外在体导电金属之下可能需要一层下阻挡金属(UBM)。
