摘要:
An RF structure that includes an optimum padset for wire bonding and a high performance inductor that contains relatively thick metal inductor wires, both of which are located atop the final interconnect level of an interconnect structure. Specifically, the RF structure includes a dielectric layer having metal inductor wires of a first thickness and a metal bond pad having a major area of a second thickness located on a surface thereof, wherein the first thickness is greater than the second thickness. In the inventive RF structure, the majority of the metal bond pad is thinned for wire bonding, while maintaining the fill metal wire thickness in the other areas of the structure for inductor performance requirements, such as, for example, low resistivity. Methods for fabricating the aforementioned RF structure are also provided.

RF结构包括用于引线键合的最佳焊盘和包含相对较厚的金属电感器导线的高性能电感器,两者都位于互连结构的最终互连级别的顶部。 具体地,RF结构包括具有第一厚度的金属电感器线和位于其表面上的具有第二厚度的主要面积的金属接合焊盘的电介质层,其中第一厚度大于第二厚度。 在本发明的RF结构中,大部分金属焊盘被薄化以进行引线接合,同时保持结构的其它区域中的填充金属线厚度用于电感器性能要求,例如低电阻率。 还提供了制造上述RF结构的方法。
