摘要

High performance passive components are a necessity for today's integrated mixed signal and RF circuits. Low resistance interconnects allow integration of high quality metal-insulator-metal (MIM) capacitors, lateral MIM capacitors, inductors, transformers, fuses, and transmission lines. In this paper, performance issues of these interconnect passive components and their integration into subtractive Al process and dual damascene Cu process are described. The migration of capacitors towards high-k dielectrics such as Ta_2O_5, characterization of free lateral MIM capacitors and results of integration of photo-BCB as a thick dielectric to improve upon inductor Q are also presented.
